Yeah, now looking back you'd think it's stupid to keep everything in one semi-secured safe house and only use minimal security, but at the time, these were uncharted waters. Franklin only got a taste of how fucked up the game could be last season, and he managed to work his way out of it without getting his hands dirty. I assume as the season goes on, it's going to be about Franklin learning how to be the man, and getting more ruthless as time goes on.
