Following your logic, in a situation in a hotel room where there is a grown man, who hasn't been arrested, and is not cuffed, and is simply being questioned, the one cop in the room with him should nullify any possibility of the man taking his own life? Following that amazing, stupifyingly clear and sensible logic, it would follow that Roebuck would not have been allowed to his bathroom - he could have slit his wrists with his razor/drowned himself/hung himself/swallowed any pills in his toilet bag. Likewise, the cops should have immediately removed all glass wear from Roebuck's room, just in case he broke a glass/bottle and slashed his wrists. Fact is, if an intelligent guy like Roebuck wants to top himself (for whatever reason), one cop, 6 floors up, who is simply *questioning* the guy could not stop Roebuck from topping himself if that was Roebuck's wish. Even cuffed, if the window was part open, Roebuck could have dived head first though it.
