IS McCAIN TRYING INCITE VIOLENCE?

Say it ain't so, John:
One wonders at this point how the various agencies charged with the responsibility of protecting the Presidential candidates from violence will respond to this latest tactic from the McCain campaign. If, for example, a McCain supporter threatens the life of Sen. Obama by shouting 'Kill him!' at a Palin rally, should Sen. Obama's Secret Service contingent launch an investigation?
Palin had better be careful, because this line of tact is very volatile.
