Prince Escalus threatens the citizens of Verona with death if they ever disturb the peace again. He holds them responsible for allowing the feud between the Montagues and Capulets to spiral out of control.
Escalus did not sentence Romeo to death because he believed that Romeo acted out of love and in response to Tybalt's killing of Mercutio. Escalus also considered the circumstances and Romeo's previously good reputation in the city of Verona. Instead of death, Escalus decided to banish Romeo from Verona as a punishment.
After the first brawl in Romeo and Juliet (Act 1 Scene 1) Prince Escalus announces that in future street fighting will be a capital offence (punishable by death). Prince Escalus isn't exactly clear whether he means all street fighting will automatically be punishable by death, or only streetfights leading to murders (lots of characters in this play have trouble saying what they mean), but certainly when Romeo kills Tybalt there is a good chance that he will be facing execution. This is why he has to leave Verona.
He says they have to lay off the fighting or he'll have them put to death.
Romeo gets banned from Verona in Act 3 of William Shakespeare's play "Romeo and Juliet" after he avenges Mercutio's death by killing Tybalt. Prince Escalus banishes Romeo for his actions, declaring that if he is found in Verona he will be immediately put to death.
