Prima facie (see what I did there?) it seems unlikely that the police want to canvass an entire area for a burglary (though they obviously do that for more serious crimes), though we don't know the specifity of the area - might just be your house/street and might be legitimate. Am surprised they didn't/couldn't confirm the name of the cop in question, though.

On the letterhead/quality, I am kind of glad that the Met isn't spending much money/time on reprographics.

As I was arriving at FH station this morning there were 4 PCSO's - they seemed to be chatting to random individuals on Platform 2 (and were looking in at least one bloke's bag). Is this related? I have to admit I didn't stop to see what it was all about (though I am naturally inquisitive - or "nosy" as some people call it - I was mainly concerned with catching the train).

Maybe slightly off-topic, but a couple of weeks ago I got chatting to some very helpful plain clothes cops on Perry Vale. Nice to know they're around if needed, and they provide a good complement to the uniformed police who also seem to be out of their panda cars and walking the beat a lot more recently.
