Cliff hanger. You had me wondering what he was going to be in trouble for, and I expected they were going to charge him because the nice, friendly, forced-entry home invaders were "trying to flee"...
But so far, it seems he is only in trouble for being a felon with a weapon.
Now, it doesn't say some critical details. If the gun belonged to someone else, a felon is allowed to use one for an immediate need, but would probably have to prove how he is otherwise not in possession.
Also, it matters to ME, what his crime was that made him a felon, even though the law won't care.
As for "trying to flee," it sure seems like the second guy should have been long gone by that time.
