This in no way excuses the ludicrous use of force by the police, but… They forgot the keys, so they broke their own window to get in? who does that? It’s an apartment, call the super? or a locksmith? Get called to a break-in, see signs of forced entry, see someone coming to the door with a gun… Yeah that’d be intense all right. Doesn’t excuse the police actions but dang. bit more understandable
