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.

Verify if the sentiment of the following document towards the entity George W Bush is Neutral . Bush should have fired both men . 
There 's been a lot of talk lately about George W. Bush 's legacy in Iraq , and what it means for his brother Jeb 's hopes of following him to the Oval Office . 
When he was first elected , in 2000 , Bush 's rough-and-ready demeanor had a Harry Truman cast . 
Bush 's incompetence was ultimately responsible for the ineffective federal response from August 29 to September 2 . 
Bush , furthermore , embarrassed himself by flying down to the Gulf and claiming that "Brownie" was doing "a heck of a job ." 
The national media rightly ripped into Bush like never before . 
More than any other event of his White House tenure , Bush 's slow response to Katrina made Americans ask if he was a "bunker" commander , relying too much on cautious paper pushers such as FEMA 's Michael Brown and Homeland Security 's Michael Chertoff . 
After the attacks on the United States on September 11 , 2001 , Bush was virtually unseen during the first 11 hours , making only brief statements and effectively ceding the public leadership role in the crisis to New York City mayor Rudolph Giuliani . 
Politically , Bush was wounded , never to fully recover , his standing made all the worse as the economy tanked in 2008 . 
Just as New Orleans 's levee system catastrophically failed to work -LRB- breaking in about 50 places -RRB- Bush had catastrophically failed to save lives . 
Bush chose to fly over New Orleans in Air Force One instead of doing an on-the-ground inspection -- a clear sign of aloofness , indeed , of fear . 
Even George W. Bush 's most stalwart supporters cringed at his disconnect from reality . 
Bush , like Michael Jackson in his days at Neverland Ranch , was living in a bubble . 
Bush was , quite simply -- as Coast Guard first-responder Jimmy Duckworth phrased it -- "out of the game ." 
Instead , Bush monitored developments mostly from afar . 
On the 10th anniversary of Katrina , with the advantage of hindsight , it 's clear that Bush 's lack of leadership in late summer of 2005 cost his presidency mightily . 
Unlike Ronald Reagan , after the Challenger explosion , or Bill Clinton , after the Oklahoma City bombing , Bush had failed to feel the profound implications of the moment as his predecessors had . 
But Bush -- a private man by nature -- was never a particularly accessible president or an outwardly sensitive one . 
Instead , Bush acted as though he were disinterested in the natural disaster . 
No matter how the Bush library in Dallas tries to spin Bush 's Katrina performance , we all know he deserved an F in crisis management .
