Here's a good reason to upgrade the front door and door-frame so that beat cops don't have the tools to enter . . .
When I was a kid they aired TV footage of a police raid on a suspected drug house. It’s been a lot of years, but IIRC, the whole thing went something like this:
The cops announced, and almost immediately started pounding on the door with sledgehammers. (This was before they had either SWAT teams or battering rams.)
No response. Door didn't move. In due course, a small window in the door opened - just like an old speakeasy - and a face looked out "What'cha all doin' poundin' on mah door like dat?"
"Police! Warrant! Open up!
"If'n youse gots a warrant, youse gots ta show me dat. Show me da warrant!" Went back and forth this way a few times.
Much shuffling around - who has the warrant? Nobody knows.
"Open up! You have to open up!"
“Ah already says, not ‘til you shows me da warrant!”
FINALLY the warrant is located, and a cop waves it at the door. “Here’s the warrant! Open up!”
“Hold it up so’s I can read it!”
Cop does so, and the door opens. Bunch of chroirboys sitting on a sofa inside. Door has been reinforced with what looked like 2x12’s on the inside, and a bar like on an old castle across it.
“Why is your door so strong?”
“Dis be a high crime area, and you cops is never around when youse is needed.”
No drugs found . . .
