There are devious, tiresome burglars out there who will sit in your toilet for hours on end reading Proust or doing cryptic crossword puzzles and using all the paper, and leaving floaters and other debris, and there are very modest, diffident and nervous burglars who will slip in for a quick wee-wee before rifling your silverware and who will always lock the door in case they are caught with their flies undone, and then there are burglars who specialise in the shiny metal IKEA brush holders, which now fetch a premium, what with aluminium prices going through the roof.
And then of course there are narcissistic burglars who insist on popping into your WC during a caper in order to check their striped shirt and mask and bag marked "SWAG" in the vanity mirror.
Fortunately, very few of these burglars (and absolutely no "totally incontinent burglars" - the very worst kind of intruder) are known to carry military-grade automatic firearms, and they are therefore not usually THAT dangerous, and one doesn't need to drill them full of holes through a closed door.
Except...
if one is completely out to lunch on bad acid or crystal meth or similar, when it probably doesn't matter, as the burglars manifest themselves as giant flying lizards anyway.
Seriously, has the toxicology come back on OP yet? I can't help feeling, however hard I try to get inside the tingling skin of someone living in a scary place like this was alleged to be, that he must have been utterly bat-$h1t crazy at the time. Drugs will do that to you.
