We see a flashback involving a man and a woman on a stakeout somewhere in the country. The FBI team encounters a boy who runs back to the house, grabs a gun and starts firing at the agents. Other family members then join in and several individuals on both sides of the subsequent gun battle are wounded. Finally, the woman turns around to see a woman aiming a shotgun at her and we hear that weapon go off as the scene ends (and we learn that several people were killed during that).
There's an intense car chase in which a man pursues a van. The man sees his kidnapped son in the van. The man chases after the van with the bomb. Two cars crash into each other and later one of those smashes into a bus and is spun around. The cars finally stop, and both drivers get out. A man in another car stops and punches the pursing driver several times.
We see a brief shot of some people who've been hanged as well as a few out of focus photos of somewhat bloody victims of terrorist attacks (as well as pictures of a destroyed building).
A man throws another man up against a car and punches him in the back. He then drags him into a deserted building and hits and kicks that man. The latter eventually turns the tables and repeatedly punches the first man until his face is rather bloody and then briefly pushes down on the man's throat with the weight of his foot.
There's talk of a person dying from a gunshot wound in the past (that may or may not have been murder) as well as recently on a TV news report (we see neither).
