This is a false dillema. Show me any evidence that massive surveillance increases security.

There are many things that increase peace and security: wealth, education, good institutions/political systems, arguably culture, etc. Surveillance is probably not one of them.

I agree with your opinion. But the problem is that: every option in your comment is a long term policy, it can't resolve the current problem in the reality as quick as possible.
