Did you mean "random-ass search", as in searches without reasonable suspicion, or "random ass-search", as in inappropriately adding a body cavity inspection to an otherwise justifiable search?
The fact that I cannot determine this from context may be a problem all by itself.
And while it's true that there is usually a reason for throwing people in jail, that reason is often an arbitrary, capricious, or morally dubious reason. I prefer that people go to jail for doing a specific, non-accidental harm to someone else, rather than doing something that merely offends a moral principle held by someone else.
Get high on a PCP dipper, and you are only hurting yourself. Get high, strip naked, and go out to jump on top of cars, and you might do time for all the auto-body damage, proportional to the cost of repairs. Get high on heroin, and you are only hurting yourself. Share some of your heroin with someone who doesn't know how dangerous it is, who then dies from asphyxiation, and you might go down for negligent manslaughter. Get drunk on alcohol, and you are only hurting yourself. Get drunk, and then try to drive home, taking out 14 mailboxes and one step-down transformer, and you might be doing some time.
...unless you have money, or know the right people. One of my former bosses occasionally mentioned at work that he grew weed inside his house. He probably went months without ever even seeing a cop. No suspicion means no searches, means no evidence, means no prosecution, means no jail. I have known people who drove drunk on at least a weekly basis, and never got cited for it even once. They all either had money or a few cop friends.
It isn't just that the justice system is not enforcing malum prohibitum offenses among that class, but they also look the other way for more serious malum in se crimes. The rich can afford more skillful lawyers. The connected can get the police and prosecutors to back off a bit.
I know someone who quit a prosecutor job because she got tired of putting people in jail for being poor. That's what modern policing is doing. It's packing the prisons with poor people and the jails with the untreated mentally ill. I didn't vote for this. I don't know anybody that would. Yet the people around me keep electing representatives who promise to be "tough on crime" and the "law and order" candidates, without stopping to consider that those people may be inventing new crimes just so they can get tough on them, or that their new laws may encourage more civil disorder.
