I brought 2 cans of peper spray with me for London - Singapore tour last summer and I will carry it again in future. Its a very personal choice, I was glad to have it along alone for the pscycological effect of having a last resort. Its up to you and the situation if and when to use it. I had an uncomfortable situation in Diyarbakir, E. Turkey, where I whipped it out and it was a huge relief to have it when I thought the alternative was handing over my beloved bike. Mind you I have'nt heard of anyone ever having had to use a waepon. If you got it with you you have the option to use it. If you don't then you don't!
