And this shooting displayed that the common police equipment of the time (pistols, shotguns) were ineffective against determined and well equipped criminals. Police wanted handy, precise rifles (AR-15), and better armour for themselves and vehicles in case of emergency.
So the police looked to relatively cheap mil surplus and things that were compatible with them, fast forward a few decades and that is why the police have a ton of military grade gear.
