Not that they were justified in this case, but something like this this is what’s used.
I think we still need to know what kind of door lock these folks had. If the police were standing there firing at a padlock on the outside of a home I'd have to doubt their mental ability. If just an ordinary passage lock they could have busted it with a hammer. The type of locks I have wouldn't have been bothered by that breaching load but it might have knocked a hole in my metal doors.
We had a lock failure in the door leading to our men's room at work. Couldn't get in. Fortunately we could use other facilities elsewhere in the building.
This lock had a titanium housing. It couldn't be bent, banged on, sawn, or whatever. I got one of my carbide tipped machine tool drill bits (appropriate for boring holes in Engine blocks) and busted it up in a couple of hours.
That lock impressed me although I had to question the wisdom of the guy who thought it would be good to use such a device INSIDE a building for a very high use room!
Fasinating...
I stand corrected.
