Truth is I don't know how I'd react.
And as with any weapon, the perp will be more used to violence than you
and as a result take it and use it on you!
And carrying it is classed as an offensive weapon in the UK.
(Which is just wrong, a person should be allowed to arm to protect themselves from evil people who mean us harm.
Response times' mean the police certainly won't be there to.
Self defence weapons
and appropriate training in their use should be allowed,
but they're not. Thanks nanny-State.

Self-assurance can go a long way to convincing a perp you are too much trouble.
Self defence classes are specifically good for this.
