Sigh.
No, I don’t - I just don’t think you are the authority who gets to decide why certain trends exist, because you obviously can’t know. This isn’t controversial.
I can speculate that personal theft is way up because everyone now carries a smart phone, as well as a huge increase in the prevalence of tablets and laptops compared with 30 years ago - it’s probably true that would contribute and it seems a logical assumption, but guess what? I can’t prove it and I don’t know if it’s true.
It would be a theory, exactly like yours.
