Are we really safe?

The way media person Jamim Shah was killed on broad daylight highlights the threats to our life and make us wonder if we are really safe. The mystery killer was found out only after a week or so after his murder. The case made me think if the police who is responsible for our protection also gets involved in killing then how safe we really are? If it is so easy for the people to kill and run away then what are we going to do about our life. its so uncertain, everything is so uncertain in this country. The killing are increasing in the name of ransom, revenge and other reasons. The reason for Jamim's murder, however, has not came to light. It is a matter of serious concern for all the people. Why don't people just live and let live?
