One reason why certain people prioritize "Law and Order" above empathetic solutions (i.e. child support, after-school programs, etc.) is that they are not guided by a moral bearing.
They don't understand that they can be self-motivated to not to bad things to others.
They are only motivated by the potential retribution of their local community
Or, ultimately, motivated by Law and Order.
They cannot empathize.
They cannot understand that others can empathize.
Therefore, "lock 'em up!"
