Re: Going equipped
I believe it also has something to do with how you answer any questions the police might ask - e.g
Polis : "I see you have a perfume spray there madam that isn't the perfume you are wearing..."
Woman: "Oh yes, that's so if someone attacks me I can spray it in their face and get away"
Polis: "...and that'll be considered an offensive weapon, if you'd like to accompany me to the station"
Now obviously you are allowed to carry perfume sprays, just not with the intention of using them as a weapon - same with many other things like wrecking bars, pipe wrenches. You just have to have a good, legal, and preferably verifiable, reason for carrying them, and for the most sensible law enforcement officer to be having a good day.
