Input: Consider Input: 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.

The gap in time led to questions about whether  Johnson  was killed in the assault and not found  or if  he  was taken away by the enemy.
According to the officials  a medical examination concluded that  Johnson  was shot as many as 18 times.
It is believed  he  died in the attack and there were no indications  he  was shot at close range  or had been bound or taken prisoner  as several media reports have suggested.
