Everytown for Gun Safety
Following the Stoneman Douglas High School shooting on February 14, 2018, they and their puppets stated that the shooting was the 18th school shooting of the year, by including many such absurdities as suicide in the parking lot of a Michigan school that had been closed for seven months, or a stray bullet that hit CSUSB (with no shooter on or near campus), as "school shootings". USAToday, Time, WaPo all reluctantly admitted it was "flat wrong". The real number was 4. And this wasn't the first time Everytown got caught for doing the same thing: they were criticized after Sandy Hook Shooting (inflating the numbers by 4x). And their website refuses to correct itself. They're the SPLC of Gun information.
Well dishonest is one thing, but how dumb are they? Based on a tweet, they don't even know which end of a bullet goes towards the bad guys. (They show a propaganda picture they took, with the magazine loaded wrong, so the bullets wouldn't fire). This exemplifies what they know about guns after 12 years of specializing in informing the public about them. The guy that mocked that tweet (andyrutledge) of course had his twitter account blocked for disseminating unpopular truths with lefties.
Everytown for Gun Safety Lobbyist Arrested For Assault, Domestic Violence, False Imprisonment. Imagine the coverage if an NRA spokesperson was arrested for that, it would be all over the news. But since it was a progressive organization, there was practically a news blackout on this.
