I was going to suggest that you obtain a concealed carry permit, but that's probably not an option if PEPPER SPRAY isn't allowed where you live.
Seriously, has anyone ever died of being pepper sprayed? If I were you, I'd say **** the law. The cops can't save you, they can only investigate after the fact.
If I ever decide to be a criminal, I'm going to the UK. It must be nice to know that none of your victims are allowed the means to defend themselves.
Ehh, I'm sorry for the rant. I really have nothing to contribute here. Carry on...
