Those guys were meth heads and wanted to die
Not true, if they wanted to die, they wouldn't have been robbing a bank, or wearing body armor, using pretty major firepower. They thought they would get away with it...As they had before.
In the the North Hollywood BofA robbery, both suspects were not only armed with auto weapons, thousands of rounds of ammo, but were wrapped in body armor in addition to home made trauma plates...LAPD was not only out gunned, but the suspects were pretty well protected...
With 18 minute both suspects were dead, as officers literally went head to head with them even though clearly outgunned.
Which made it worse than a equipment/gun issue withe the LA cops vs them. These guys not only didn't give a fig, they wanted to go out blazing. Until the end,when the one tried to hijack the car. By the way, I think the LA cops purposefully let the guy bleed to death. Not that I blame them, at all.
