Property is something you own by law - for example, a factory, acres of land, an idea, rights to do this that or the other, someone elses' work. It contrasts with...
Possession. Something you *physically own*, for example, your toothbrush or radio, or smartphone, or (at a stretch) the house you live in.
We oppose the former, but support the latter.
"not the average bobby on the beat"
And when was the last time you saw one of those?
In my area of North London it's weeks maybe even months between sightings.
Last? Earlier this morning. Time before? A couple of days ago. Any evening I go out into town there's a few wandering. There's usually one patrolling the rest of town too. I'm not fan of the police, but I see them quite often.
