Suspected would-be Trump assassin Ryan Routh seems like “someone who is constantly trying to poke somebody and see what their response is going to be," former FBI special agent said.

The suspect in the apparent assassination attempt against Donald Trump currently faces gun charges, but ex-prosecutors say a lot more is on the table.

Another way Routh may have gotten his gun was by buying it legally before he became a convicted felon. Drane said hundreds of thousands of prohibited people still maintain possession of their firearms because no authority forced them to relinquish them.
