Arorasky, I'm glad you called the police about him. I understand now where you are even self defense items like pepper spray are not legal.
Just some other way of looking at things
Pepperspray or mace is not about being armed as some have suggested. Where legal to have, it is a last chance defense for a situation where the attacker has already cornered you and gotten too close making avoidance or running impossible.
The idea of a male friend is more about simply giving the stalker the feeling that you are not alone. If the person is of criminal intent he will normally avoid choosing a victim who is seen to be in a group. If two or more people are seen traveling together most ill-intending persons will think twice before attempting something. If the group is seen regularly the stalker may loose interest. It is not a passive aggressive game. It is basic animal psychology.
