I would be.
I live in a very quiet area, but I have had a load of "scrap" nicked from the back garden and they are bold as brass when they do the deed. I was told by a neighbour the guys pulled up outside my house in a transit, they were challenged but replied that they were sent here to collect an old dishwasher, so off they went in to my back garden, nicked a load of "scrap" which included my original 1.6GTi alloys and a steel bath I'd only just removed the day before (how did they know about that?!)
This was when scrap prices were very high so theft was tempting. Quite low prices now so maybe not worth their bother.
Oh, and Police didn't give a stuff, didn't even bother. They could have gone to the local scrap weigh in place where I could have identified my alloys :evil:
