Snatch Thieves

Why are there so many snatch thieves in JB, Klang Valley and other towns?
Are there many people left jobless?
These trained group of nonsense is doing it again and again daily.
It is kind of habit to them. "Hunting" is the word.
Human being with binocular vision are born hunters. We all know that their victims are not born with monocular vision. Victim who carries handbags carelessly and talks on the phone while walking might have not been attentive enough, did not care about the danger confronting them.
These snatch thieves too were born with equally two hands and legs and I do not understand why they like to harm other people.
