Has Anyone Seen The Video Of The Second Suspect Dropping The Backpack?

FBI says they have video of the surviving suspect dropping the backpack.

“Suspect 2,” wearing a white baseball hat backward and dark clothing and carrying a light-colored backpack, was videotaped setting down what the FBI believes was the bomb that caused the second blast outside the Forum restaurant on Boylston Street near the finish line. The man then walked west on Boylston, but federal officials said he remained in the general area until the bomb went off.

So I go to the FBI website which has the videos of the two young men who live in Boston walking around

with backpacks.

Yet there is no video of the second suspect dropping the backpack. And the cops say they have no video of the 1st suspect dropping the backpack.

If the FBI actually had the video of the suspect dropping the backpack off, and then I would assume they also have video of the pack actually exploding, wouldn’t they at least show him dropping the pack off to show the public they have the right suspects?

As far as the story from last night to now, who knows what to believe?
