Well, depends if the life sentences were congurent (you get 5 lifetimes, but you do all those at once) or consecutive (you do each life sentence one after anohter). Either way, 7yrs is fvcked up.
Tougher sentencing? Yeah right, when the time comes people are so hypocritical about it. Remember the white boy that got spanked in Singapore? The entire US was in an uproar... even President Willy got involved.
Personally, i don't believe tougher sentencing is the answer. Because it hasn't been! Look at the US, which has one of the harshest sentencing and laws, yet the crime rate is the highest in all the industrial world. Obviously locking ppl up forever is not the answer. Not only will you run out of room and resources, but EVENTUALLY ppl ARE let out. All you're doing is treating the symptoms. You're involved only when the outcome has resulted. American people don't like prevention, because it's often difficult to measure the effectiveness of it. When you sentence somebody to life, the outcome is concrete, the victims family have closure. But when you spend money in preventing crimes, you don't see the effect of it so clearly... only when you begin comparisons with past numbers do you, and even then, eventually ppl will forget it's the prevention that was effective and they will pull out the prevention methods. Take the campaign against crack use in the mid 80s. A very effective campaign that resulted in a dramatic decrease in crack use up until the early 90s, when there was no longer a 'crack problem', then the campaigned was pulled... now the problem is coming back.. and new measures won't be introduced until it becomes a serious problem again.
As for the death penalty. Well, unless you can be 100% sure that no innocent would EVER be put to death, then in my opinion it's just not worth it. But is your justice system that foolproof?
