This is the age old question. How much freedom should we give up to have security? If we look at London England for example, they have perhaps the most surveilence of any place in the world. They also have some of the strictest gun controls laws in the world (guns are a privilege there and not a right), and their police essentially do not carry guns either, with only specially trained field officers carrying guns(more similar to a military unit). In its purest esence, they live in a police state,  and their crime is rising and not decreasing.

I would argue their so called security is nothing but a sense of feeling safe, and perhaps even  less safe then we are.
