Can the police force, however, it's not like they just go out and detain people or try to hurt and kill people for fun . However, they will come into a home ready, and that's just the smart way to do things. My mother works in cancer and tuberculosis treatment, so she wears a mask and gets tested for tuberculosis. Yet he's in a tube and never even touches her, because the hospital knows how bad it can be. Why is it seen so negatively, when the police use the same idea? Yes, obviously they don't test for TB, but the same idea applies. This idea is: mitigate everything you can, hope for the best, and be prepared to do anything.
