They should be afraid of the people, but not of individuals with guns or money to hire contract killers.
Kirk’s death was a public assassination. There are many easier for ways someone can kill an unsuspecting target. The way the killer escaped makes it likely they where professional or otherwise trained, not just crazy. The killer choose a difficult and public way to kill him, meaning it is more then just about killing Krik. It is clearly a message, question is what message and to whom.
Maybe you are scarcastic, but I think nobody should be afraid of their life by getting killed by random people.
