Man you dudes in here are missing the big picture...
Yeah it's cool when people are getting murked or not, but it's not going to help in the future.
If this fool Rick starts killing all of the other stong people when **** hits the fan who's going to be there to back him... the women

They're going to be treated like cattle and raped, sold or whatever if they run into a strong group of men.
This dude Rick is not thinking properly he's just straight up doing things for the moment... when he should be thinking about the long run.
They should be building up their group with as much strong people as they can and start taking over other groups and then everyone will have one man and one woman to themselves.
Another thing I think they should do is not kill walkers but keep them alive and up them all around the jail to deter others from coming it. Like use the walkers as a security barrier or a moat of some sort that way when someone sees the prison they'll see it has so many walkers they'll move onto something else.
They have the right idea though with growing some food, but Rick is not thinking about the strength of his pack. If they run into a group of men they only have two strong guys which is Rick and Daryll... then Maggie is after them... then T-Dogg... then Glenn... then Carl... then the blonde girl... then one footed Hershel... then Lori is last since she's so useless.
On another note though my dude Rick is on some straight up F Lori **** lol... wouldn't even acknowledge her as a wife
