The police didn't give us any details, but there's talk that they are partly to blame for what happened. Apparently, just an hour before the incident, one of them was near the scene of the crime, possibly even in the victim's house.
And who visited Gil besides the cops? Special forces? Let someone else protect him if he needs it. There should always be one cop with Gil. Who else is there... a detective, a doctor, a pimp... the doctor is probably dead, the detective might be too. The pimp is probably not stupid enough to go to Gil...
