You sound soft. Putting people in jail only makes you pay for their existence while they become better criminals.
The only people jail deters are law abiding White men, who do not want to be lumped in with feral niggers.
Execution is the way. Not even deportation is the answer. Just start executing motherfuckers for crimes and the crimes will stop. This is my standard answer for the border invasion also. Start shooting them as they cross the border and leave the bodies lay on the field in the north or the river in the south. People will not cross after that see that shit there.
Most people, simply do not deserve to live.
Look at El Salvador. They locked up a sizable portion of their population in a short time and put them to work. They more than cover the costs of their incarceration. As their president says, they are helping to rebuild the nation they destroyed.
Also, their prisons are not a pleasant place, even for people who are used to living in slum conditions.
Prison doesn't rehabilitate, it just produces a financial drain on society.
I am pretty sure those prisoners in El Salvador are not putting into the economy what it takes to build, staff, and maintain the prison. Then add the costs of food and hygiene items needed to house people in mass. Not to mention the medical care of them fucking and stabbing each other.
Of course prison isn't a pleasant place. This is why the average White man is deterred.
