You can always execute me later. Or the Blues might come at night. But what if all the Mafia suddenly decide to finish off the city, which has already suffered quite a bit? That wouldn't be pleasant, would it? And we already know a couple of Mafia members.
Okay, let's say we hang Mafia-Links now. What's the point? We won't eliminate the group, and they'll still shoot tonight. So what's the benefit of executing someone else?

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
