We as society need to respect each other instead of treating everyone like a bunch of thugs.
And I'm with you there. Laws ultimately do not prevent crime. Good will and respect for everyone else does. However as much as want to believe in the goodness of human nature, I have to recognize that many individuals do not possess those virtues. Therefore laws are stablished to deal with the aftermath, and to certain degree make us feel secure. And notice that I say "to certain degree".
