Q: Verify if the sentiment of the following document towards the entity David Clarke is Positive . It's not enough to tell people that if they see something  they should say something  as often  people do not know what to watch for and report   former Milwaukee County Sheriff David Clarke  said Tuesday.
"There are a lot of people  350 million people in the United States  " Clarke  told Fox News' "Fox & Friends" program  while commenting about the deadly Las Vegas concert shooting. "They are not all known to law enforcement  so where I would start is doing a better job of engaging the public to help us out."
 Clarke  described Paddock Tuesday at the "needle in the haystack reference that you hear in homeland security enterprise and environment  and at times like this  the call to report troubled people starts over.
"We don't tell people specifically  you know  what to do  what to look for " said  Clarke . "I have been in law enforcement for nearly 40 years. I'm suspicious about everything."
 Clarke  said  he  has no doubt that as the investigation unfolds  there will be details that are now obvious in hindsight.
"We [should] do a better job of engaging the public  say here are the sort of things you need to look for and an ongoing campaign to do that " said  Clarke . "We spent a lot of money to see something  say something campaign. I wonder what the results are."
News broke Monday that Paddock's father had been on the FBI's Most Wanted List back in the 1960s  and  Clarke  said it will take a behavioral scientist to unwrap the shooter and  his  motives.
"We saw it in Orlando " said  Clarke . "We saw it in San Bernardino. We saw it a Fort Hood. After a while you look and what you hear over and over again is like some of the people's closest neighbors and friends saying 'hey  he seemed like a normal guy to me.' Oftentimes not."
 Clarke  said  he  expects Paddock's girlfriend  Marilou Danley  who was out of the country at the time of the shooting  will shed some light on his motives.

Q: Verify if the sentiment of the following document towards the entity Paul Khairy is Negative . The excitement of sports is likely responsible for the observed increases in heart rate  said study author Dr. Paul Khairy  a cardiologist at the Montreal Heart Institute.
But the new study is the first to demonstrate that the ambience of a live game â being surrounded by cheering fans  being closer to the action and experiencing an increased level of engagement â may all contribute to the heightened emotional stress response in fans   Khairy  told Live Science.
In the study  the heart rates of fans who watched a hockey game in person increased by 110 percent  on average  from their resting heart rates. That's comparable to the increase you'd see in someone running  jumping rope or doing any other vigorous form of exercise   Khairy  said.
Fans who watched the same game on TV had a 75 percent increase in their heart rates  on average  which is similar to the heart rates seen with moderate physical activity  such as a casual bike ride   Khairy  noted.
Surprisingly  a person's interest in the sport and engagement as a fan were not linked to changes in heart rate during the game   Khairy  said. However   he  added that  he  suspects there might have been a different result if researchers had developed their own way to measure passion in hockey fans rather than adapting a tool originally designed for soccer spectators.
Although fans watching any sport can experience a similar amount of excitement as was observed in this group of hockey enthusiasts  these results may not apply to other sports   Khairy  said. There are too many elements that differ among sports â such as the pace of the game  a fan's emotional attachment to a team  and even the number of high-intensity moments â that prevent researchers from making similar generalizations   he  said.
A fan's emotional reaction to a game can be intense   Khairy  said  and that could trigger cardiovascular problems.
Fans who experience cardiac symptoms during a game should seek immediate medical attention rather than waiting for a convenient moment  such as in-between periods   Khairy  said. Many arenas and ice rinks have cardiac defibrillators on hand  as well as people trained in using them   he  added.

Q: Verify if the sentiment of the following document towards the entity Mark Zuckerberg is Positive . In the wake of the Russian troll campaign against Ukrainian activists  several Facebook users brought up the issue to  Facebook co-founder and CEO Mark Zuckerberg  when  he  called for questions to be submitted prior to a May 2015 town hall  the report found.
 Zuckerberg  touched on the issue during  his  town hall in May 2015 and said that several posts that had been flagged contained "hate speech" and anti-Russian "slurs."
" We  did the right thing according to  our  policies in taking down the posts. I support  our  policies in taking down hate speech "  he  told attendees.
 Zuckerberg  extended an apology to users whose posts had been taken down despite being in compliance with community standards  and attributed the error to a bug in Facebook's software.
Former President Barack Obama tried to warn  Zuckerberg  about the threat of fake news and  its  effect on the 2016 election less than two weeks after Donald Trump won the presidency The Washington Post reported on Sunday.
Nine days before Obama warned  him  about the effect fake news had on the November result and the problem it would pose in future elections   Zuckerberg  struck down the notion as a "crazy idea" that "surely had no impact" on the end result.
Following the president's warning   Zuckerberg  acknowledged the problem but said fake news wasn't widespread on Facebook  according to The Post.  He  added at the time that there was no easy solution to the issue  according to those familiar with the matter.
