Lt. Jackson was a good guy!!!
I agree with Jackson, and i think, most of the time, he was doing the right thing. I mean i know, he could get carried away sometimes, but thats coz of the pressure of the job and life, and 6 times he's had on him, thats the reason he was so tough on the cons. Also the guys in his prison where scum anyway (except for wade, as he was in there for the wrong reason and Jackson didnt really know that), killers, rapist, etc, who would do the same once they get released.
So i think, Jackson was doing the right thing, by being so harsh with these kinda scum, trying to break em down in anyway he can, coz he knew that just by being locked up, these guys aint gona change for the better.
In his normal life, Jackson was a pretty decent guy, i mean he wasnt the sort of guy who'd hurt other people, but rather he liked to protect society from such scum. I know he did do pretty hardcore on the guy who ran his kid over, but that was coz that guy had 3 strikes already, which makes him a criminal, and he was a danger to society, running kids over and he aint gona learn or change unless its the hard way. So even there im with Jackson. If we had more of such guys, this world would be a much better place and criminals would be *beep* scared. Thats just my opinion people
