for what do the law andthe right exist？
think of ethical.for innocent people to live safely to defend from crime.
i am confused now.it seems that many people take more seriously criminal than
victim on the right.conflicting right.confliting laws.the brutal homiside is
defended by both of them.the lawyers try hard to justify the crime.
why dont you notice its wrong？an eye for an eye.
