they didnt go the house because security sent them after an alarm was triggered.
they went to the house because Pelosi dialed 911 ..left the line open..and the 911 operator sensed something was wrong and sent a priority wellness check through
That appears to be the case, yes. Doesn’t mean there wasn’t an alarm also.
I really only see a couple of options here.
Drunk Paul forgot to turn on the alarm system.
Drunk Paul let the dude in.
Drunk Paul doesn’t have a security system that alerts police - which is not plausible.
