But would you be sure he wouldn't kill someone else and that other family would suffer? Yes.
I wouldn't feel more safe 25 years after, when he gets out of jail. Maybe he could do it again, to your family or you. He killed, he is still able to kill.
I'm not saying he would do it, but he could.
A particular woman named Karla Homolka just got out of jail. She tortured and killed 2 (I think just 2) girls with a partner named Paul Bernardo.
They're media moguls here and everyone wants her behind bars still. But when a killer is released into society, there's so much spotlight on them that they have no freedom. Everywhere they go, someone is reporting on them, someone is following them taking pictures and publishing articles about what they do. They have no privacy.
Noone can ever be sure of anything. Everyone has the potential to harm anyone, and it's freedom and trust that we put into each other that you don't.
For some of these people, getting out of jail is worse than being in it.
And it should also be noted that when a killer gets out of jail, they're examined by a highly trained and experienced panel of judges to determine whether or not they're a threat to society, and if the person
is mentally unstable, many precautions are taken to ensure the safety of free citizens.
You speak as though the free citizens are the only ones at risk, but you're forgetting that the penitentiaries are also filled with hundreds, sometimes thousands of other inmates who are just as at-risk of being killed by that murderer as someone on the outside (once the murderer gets released). Whereas sex-offenders are more likely to repeat an offense, this is because they have uncontrollable impulses and a mentally unstable drive towards that sort of crime. Most killings are from impulse reactions, whether it be out of fear, hate, or profit.
Of course, there's also the occult killings, which are an extremely rare exception and barely ever happen, save for the Manson killings (which were in essence mentally ill ones anyway), but those people don't get released anyway.
My point is, is that law officials take every precaution they can to ensure the safety of law abiding citizens if they thought the person was a threat they wouldn't be let free. Almost every person who's killed out of reactionary impulse (not compulsion) learns from their mistake. It's always in the back of their mind, that if they don't be carefull about what they do, then they'll go back and never be let out again.
I liken it to homophobia. Many, many people are extremely afraid of gays comming on to them (not only men, but some women too), and it's completely irrational. You're not in harms way, and statistics have proven that heterosexual people are many times more likely to be responsible for some form of abuse, yet many people are afraid of leaving their children or being alone with gays. The same is true for one-time murderers and those convicted of man-slaughter. It sounds like a huge difference, but really, the public mentallity about the two are basically the same.
