I don't believe that. The cultural attitude they bring with them is firmly in the "if I can get away with it it's not a crime" category...
Here's an interesting link.......our DEA's 'most wanted'.
Don't know if the majority are 'illegals', however the majority sure seem to be hispanic.
Check out Denver, with 59 listed & 56 being 'hispanic'.
Wonder why DEA doesn't list immigration status ?? Don't they ask *either* ??
