re: What can be done to prevent more Cruzes and Parklands?

"I want solutions."

OK. As far as the government is concerned this is the solution:
#1.Force people to fend for themselves instead of propping them up and making it possible for them to be comfortable without making good choices.
This will mean that ladies will quit allowing just any jackwagon to impregnate them because they won't be able to sustain life with more mouths to feed.
This will mean that more children will be raised in a two parent home which will solve 90% of all of these issues.
#2. Strict enforcement of laws with no leniency. Prisoners labor for their sustenance and shelter.

But if you must know, the only real solution is people need Jesus.
