Kill -9

Kill (terminates without cleanup)

Only works if issued by process owner or super user (root)

The program cannot respond to this signal; it must terminate

Essentially, for a process to send a signal to another, the owner of the signaling process must be the

same as the owner of the receiving process or be the superuser.
