The more I think about this episode, and the whole “should we kill the kid?” scenario, the more I get pissed off about how contrived it all is.  I found Dale a little irritating as a character and his speech defending Randall was badly written, but I think he was totally in the right about the issue, and it was stupid that there was not more of a debate on what to do.
Randall is a kid!  And for all the group knows, he has done nothing to deserve being executed.  The two guys back at the bar?  Yeah, they were obvious psychos and bad news.  But Randall is just one more person trying to survive in a zombie-filled wilderness.  Sure he’s going to hook up with a crew he knows are bad dudes rather than go it alone.  So would I.
Lori’s comment “I wouldn’t feel safe having him at the farm if he weren’t tied up.”  WTF?  Shane tried to RAPE HER, has been acting psycho-stalker-ish around her all season long, went completely ape-shit at the barn - so why does she not insist on having him tied up?
Darryl - every episode he was in last season, he had to be restrained at the last moment from hauling off and belting someone.  Why haven’t they killed him yet?
Darryl’s skin-head brother - Merle?  First scene we see him in, he’s assaulting members of the group, ready to off T-Dog just for being black and trying to take control of the group.  They actually WENT BACK INTO ZOMBIE FILLED TERRITORY TO TRY AND RESCUE THAT PSYCHO!!!
Shane, Darryl & Merle - all have acted in aggressive, hostile, dangerous manners and yet Shane & Darryl are considered members of the group who get to vote on whether or not Randall gets to live.
Randall on the other hand is a kid with a major leg wound (he’s not hobbling away anytime soon), who was deserted by this crew that Rick’s group are so afraid of, is considered a major threat.   This is not just characters acting stupid, this is an utterly contrived scenario.
Oh, and that big crew of 30 bad dudes the group are so afraid of?  Here’s an idea - have you considered leaving the area yourself?  I thought the whole point of staying at the farm was that it was a “safe haven.”  Well, apparently it may not be.  It’s not like there’s anything tying anybody down anymore.  Just get in the winnebago and drive farther south, sit out the winter south of the border.  I’m sure there are plenty of abandoned farmhouses with well-water between Hirsch’s farm and the Mexican border to squat on.  Ones without roaming gangs of marauders hanging about.
