The reason why the FBI is after those two guys is because the one with the white hat was on a video dropping the bomb off at one bombing location. And they both show up at both locations ... and in addition ... they are both together, following in single file.
When you’ve got a video of a guy dropping a bomb off at the bomb site, you go after him and his accomplice - and not some shadow on the roof ... LOL ...
And the pictures and video the FBI has released to the public is at these links:

I'd like to see that video, but apparently the FBI doesn't want me to. Curious.
Shadow on a roof? I’ve not referred to anybody on a roof. Why do you throw this out?
By all means go after the two suspects. BUT that doesn’t mean you ignore other related individuals.
You seem to be personally vested in this. If you or yours were in Boston, I’m sorry.
Don’t wear blinders.
