Why would they think they have to snap the lock? can't they just knock and say 'Awfully sorry, but you missed an interview at the police station, just here to let you know you need to turn up.' Or isn't that intimidating enough?
Yes - could do. But what if that does not work
What if she refuses to open the door - What if she shouts "YOU'RE NOT COMING IN - GET LOST" and then jumps in the shower.
Do the police just leave and tell the reporting person - "SHE WAS IN BUT SHE WOULD'T OPEN THE DOOR"
Then what if she does this tactic every time the police attend.
Do the police just keep trying - or keep offering appointments for vol interviews which she never attends?
How do you think the reporting person/victim feels about that? - "OH SORRY, THERE IS NOTHING WE CAN DO WITH YOUR CRIME BECAUSE SHE WON'T OPEN THE DOOR OR TALK TO US - YOU WILL JUST HAVE TO PUT UP WITH THE ABUSE/HARASSMENT/DAMAGE/THREATS (whatever the allegation is)"
Bare in mind - we do not know what the allegation is here. Has something else happened the previous night that has escalated this into a necessity to arrest her?
Who knows - we certainly don't know - so how can judge how the police have dealt with it?
