I think there are certainly the more 'honest' homeless people. But I do guess where you live. In some areas/countries being 'dishonest/dodgy' is the 'norm' and so it attracts the majority of homeless people to do the dishonest things they do.

I lived in Italy at that time and yes, nowadays italians (with the proper exceptions) are not the most honest people you can find.

(I am italian myself and I say this with a little of bitter sadness, but it is how it goes, unfortunately).
