[Q]: Verify if the sentiment of the following document towards the entity Stephen Paddock is Positive . After five days of scouring the life of Las Vegas gunman  Stephen Paddock  and chasing 1 000 leads  investigators confessed Friday they still don't know what drove  him  to mass murder  and they announced plans to put up billboards appealing for the public's help.
In their effort to find any hint of  his  motive  investigators were looking into whether  he  was with a prostitute days before the shooting  scrutinizing cruises  he  took and trying to make sense of a cryptic note with numbers jotted on it found in  his  hotel room  a federal official said.
So far  examinations of Paddock's politics  finances  any possible radicalization and  his  social behavior — typical investigative avenues that have helped uncover the motive in past shootings — have turned up little.
His arsenal also included tracer rounds that can improve a shooter's firing accuracy in the dark  a law enforcement official told AP. It wasn't clear whether  Paddock  fired any of the illuminated bullets during the high-rise massacre.
 Paddock  bought 1 000 rounds of the .308-caliber and .223-caliber tracer ammunition from a private buyer  he  met at a Phoenix gun show  a law enforcement official not authorized to comment on the investigation said on condition of anonymity.
Video shot of the pandemonium that erupted when  Paddock  started strafing the festival showed a muzzle flash from  his  room at the Mandalay Bay resort  but bullets weren't visible in the night sky.
Investigators are looking into  Paddock 's mental health and any medications  he  was on  McMahill said.
 His  girlfriend  Danley  told FBI agents Wednesday that she had not noticed any changes in  his  mental state or indications  he  could become violent  the federal official said.
 Paddock  sent Danley on a trip to her native Philippines before the attack  and she was unaware of  his  plans and devastated when she learned of the carnage while overseas  she said in a statement.
[A]: yes


[Q]: Verify if the sentiment of the following document towards the entity Sayfullo Saipov is Positive . SAN FRANCISCO â Sayfullo Saipov  the 29-year-old suspect in Tuesday's deadly New York truck attack  earned money the way many gig economy works do. He drove for Uber.
But the fact that  Saipov  raised no flags for the ride-hailing company when it conducted its standard background check shows just how difficult it is to screen for potentially criminal behavior if there is no track record.
 Saipov  drove more than 1 400 trips for Uber in the past six months. Authorities continue to investigate the suspect  who came from Uzbekistan in 2010 and settled in Paterson  N.J. To date  his biggest offense seems to be from 2015  when he was cited by police for towing a trailer that was too long.

The company's response to that incident was the same as its statement after  Saipov  rammed  his  rented truck into bicyclists  killing 8. An Uber representative said the company was "horrified" at the senseless act of violence as was cooperating with federal officials.
Uber said  Saipov  had been banned from the Uber app.

[Q]: Verify if the sentiment of the following document towards the entity Grassley is Negative . ACORN's tax-exempt groups and allied organizations  long a target of conservative ire  used more than half their charitable and public money in 2006 to pay other ACORN affiliates  according to an analysis by the tax staff of Sen. Charles Grassley  R-Iowa.
 On Thursday  Grassley called the transactions a "big shell game" and said ACORN donors may be surprised by how the liberal group known for helping the poor obtain housing and health care was spending their money. He urged the Internal Revenue Service to take a closer look.
 According to the Grassley report  charities "are being used to raise monies which are then funneled to other charities or to other organizations for purposes other than what the donor may have intended. ... Dollars raised for charitable (purposes) appear to be used for impermissible lobbing and political activity."
 "Senator Grassley made up his mind  and he didn't bother about the facts " Lewis said in an interview. "He's dealing with a lot of outdated information and decided to frame it with a predetermined conclusion. Yes  we had problems under Wade Rathke. ... And we have been overhauling how we do things ever since."
 Also on Thursday  Grassley requested that ACORN  which stands for the Association of Community Organizations for Reform Now  be taken off a list of approved charities for federal employees to donate to in an annual giving campaign.
