20 million felons, out of maybe a total population of 250 to 300 million people! No wonder you have such a crime problem in the USA. That is a huge percentage.

Around about 7% of the total population is a felon???

And now to be 'racist'. If many or most of them are ethnically based, how many of those ethnic groups do not have a record? A high percentage at least are felons.

The high crime rate is easily explained by the high numbers of criminals if those numbers are correct. And also the numbers of shootings and murders.

12 million aliens would be up to about 4% of the total percentage. Also quite a high number.
