Snatch thieves practically run wild in Malaysia. This crime has become so common that people are resigned to the fact that the police can do nothing about it. Women are taught not to carry a handbag when they go out. If they do it is just a matter of time before someone comes along on a motorbike and snatch the handbag away, sometimes causing grievous injuries to the victim.
Here is one easy way to catch them all. Place a self-exploding device in the bag that will cause a splash of bright indelible ink all over the thief. Send out undercover agents all over town carrying a loaded handbag like this. I am pretty sure the success rate will be very high.
