I definitely think so. In our neighbourhood, the crime has significantly gone up over the past year with crimes getting worse (As Finy has mentioned). But there are definitely areas I avoid and going out at night can be a huge risk.
Yes the crime rate is increasing. This can be due to the fact that the general population numbers are growing so the number of criminals could be growing. But what concerns me is the brazen attitude of thieves who dont seem to care if they are seen and the increasing level of violence when it is so unnecessary.
I still go out at night but dont stay out too late because I get tired.
