Jail time is not an indicator of a bad person. The US likes to lock up people for the crime of being poor.
That's correct. Notice, however, that I mentioned the actual crimes first, and added "jail time" as an afterthought. There are plenty of criminals who commit real crimes and don't get jail time, or even much punishment. See e.g. Brock Turner, Shane M. Piche, Zoe Reardon, George Zimmerman, Isaac Turnbaugh, etc.
But what if they don't?
Then they'll scramble to find anything they can to slander the person, such as a parking ticket
Don't forget about naughty pictures such as the subject holding mind-altering drugs such as coffee or alcohol.
