I read that he had a hammer - or something similar. Why he thought
about that ahead of time and didn't shoot out the windows is odd.

Those windows have a plastic inner layer between 2 sheets of tempered
class so shooting them just pokes holes in them and spider webs the
glass.
There is a show on the Outdoor Channel where a guy tries to duplicate
things you see in movies and they did the Die Hard, "shoot the window
with a 9mm and try to break it out" thing. It was under whelming how
little damage the Beretta did. The window eventually broke when he
used an HK MP5 (not how it was in the movie) but it was because it was
so destabilized that it came out of the frame, in one piece.
The right tool is probably an axe or hatchet that can cut the membrane
while breaking the glass.
