Get the TV movie/DVD of 44 Minutes, www.imfdb.org
It's a film based on the LAPD gun battle in North Hollywood/1997.
The 2 armed felons(who had their firearms & ammunition returned due to a court action) shot up a bunch of under-gunned LA cops.
The LAPD officers ran into a local gun shop & loaded up a few M-16s & semi auto rifles to deal with the 2 violent bank robbers.
Funny how Chief Beck or the LAPD brass don't bring that little detail up.
