Before I even begin to answer the question – Was Alton Sterling a sexual predator? – I would like to point out how irrelevant it is. Whether or not Alton Sterling has a criminal history of any kind does not matter a single bit. The circumstances of his murder cannot be justified with the mistakes of his past. Police are not agents of karma, endowed with divine rights by some magic force. The manner in which police bullets stole his life is all that really matters.
Besides that, no, he was NOT a sexual predator.
Felony carnal knowledge of a juvenile is committed when:
(1) A person who is nineteen years of age or older has sexual intercourse, with consent, with a person who is thirteen years of age or older but less than seventeen years of age, when the victim is not the spouse of the offender; or
(2) A person who is seventeen years of age or older has sexual intercourse, with consent, with a person who is thirteen years of age or older but less than fifteen years of age, when the victim is not the spouse of the offender; or
(3) A person commits a second or subsequent offense of misdemeanor carnal knowledge of a juvenile, or a person who has been convicted one or more times of violating one or more crimes for which the offender is required to register as a sex offender under R.S. 15:542 commits a first offense of misdemeanor carnal knowledge of a juvenile.
It is basically just another legal term for statutory rape. You can read more of my thoughts on statutory rape RIGHT HERE.
The only thing you really need to know is that the incident from which the charges stem were for consensual sex with someone who was definitively and biologically not a child. He would have been about 21 years old at the time, and his partner could have been as old as sixteen, which has only been viewed as prohibitively young in the western world in the last century. This in no way makes him a sexual predator.
Once again, none of this really matters. Alton Sterling was killed by cops in cold blood. He is not on trial here. It takes a special kind of scumbag to go searching for reasons to justify a heartless murder. There are no justifications and there is only one trial any reasonable person would even consider, and that is the trial of the violent thugs who shot and killed a man described by all as a gentle giant.
