There is as much evidence as anyone can guess who was not an eyewitness to any of the happenings during the week of the Boston bombings, which I presume you weren't.
At the proper time, the case will go before a judge, and both sides will have an opportunity to present their case.
Conspiracy fools like you have come unhinged with all kinds of really ridiculous speculation, and outright lies, with much of it easily proven false, and yet you persist with your nonsense.
The bullshit you post has been debunked over and again, and yet you keep regurgitating your fearmonger fairy tales, and wonder why so many people think you seriously have a screw loose.
I pity you...
