In Singapore, no one is allowed to have gun - only the authority (police etc) can have. Thus, there is no need to be afraid that someone would came into your house and start shooting. You say the police? Well.. Singapore wain the top ten least corruption list 2014..
ROFLMAO.... You can't even compare Singapore with high crime countries such as the United States and Mexico. Violent crimes are extremely rare in Singapore, as the punishments are severe. The population is law abiding. There are no major ethnic gangs in Singapore and the police force is thoroughly professional.
