Snopes is all over the place on this one.

Get Off the BS also framed Trump Tower as if it were the private residence of Donald Trump rather than as a Midtown tourist attraction at which Trump himself is rarely present. If some shadowy figure had really been targeting Trump for a violent attack, he would have been better served making use of the candidate's campaign schedule (freely available via his social media feeds) rather than breaking into Trump Tower.

but then when thy're talking about who it 'actually' was:

Anthony Shark, 54, was “walking through a secured area” along the sidewalk outside of Trump Tower on Fifth Ave. and E. 56th St. just after 10 p.m. when he was busted, officials said.

Sources said he tried to barge through a frozen zone set up for the GOP presidential nominee’s approaching motorcade.

So when it's Barry Lee Bush: "Trump is never at Trump Tower lol what an idiot"

But when it's Tony Shark: "Trump was actually there today but it doesn't matter"

I'M AS MAD AS HELL & I'M NOT GOING TO TAKE THIS ANYMORE And it starts with the greatest god dam weapon ever created and unleashed against the masses. We're in a lot of trouble! The world is a business Prophetic

HRC and the good majority of the people in DC are but puppets, just like Obama, Bush, Clinton before him of the greatest evil this planet faces.

FDR should have taken them out when he had the chance after Gen. Smedley Butler served them on a platter after their failed coup. FDR backed down to their threat of crashing a fragile economy if he jailed them for the coup attempt. An economy they made fragile.

He should have laughed at them and said "Jail?" "You and your family are going to hang from the neck until death." Treason is a capitol offense" "Should have factored that in your risk evaluation."

The country would have recovered fine. Better than fine. Minus the evil trying to take it over. The Fed needs to go. The MSM needs to go and a press that is unbiased and does the job the founders envisioned them doing. Keeping the public informed and a watch dog of the government. To MAGA, we need to start making America honest again. We are far from honest, and the people are living the lie they tell us on TV.

This part checks out about the FBI agents alleged death

I shit you not, it will not let me do a screen capture on that page. That is the original article I seen on a different site, and it has been removed from that site.

True that, but he wasn't the original source. Google "dead FBI agent gun silencer Trump" Here is one result. It is the story I seen.

I want the people to say, if Trump gets assassinated, there will be no riots, no Warren commission, civil unrest. The 1% and their families will be hunted down and killed. It doesn't matter if we get the right one, just as long as they are part of the club. Give them something to think about.

They may have killed billions for their own gain, but they are still human. They don't want to die. Especially with all that money. That is the only way to prevent them. Vigilante style justice.

Is it the right thing to do? Morally? I cant answer that. I can say if a few of the elite and or their families get taken out, that they will think real hard before pulling the shit they are. They don't give a shit about morals, or the rule of law. Why handicap ourselves when they sure the hell don't?

It is extreme, but they won't understand any other language. And continue to have us fight each other, profit from our deaths, and laugh at as us during the process.
