David Boies plans to strip teachers of due process rights state by state.

16. I don't think you are a liar, but you may have limited experience with these things....

most of the horror stories about a terrible teacher are limited to

...something that happened many years ago when teacher quality was not an issue
...a single incident where the public didn't really know what happened behind closed doors
...a second hand story without direct evidence

If someone really doesn't have a clue about their subject (English, science, etc.), then there must be a reason they were put in the classroom. You simply can't take 8-10 science courses in a college major; pass a state test in chemistry, biology, or physics; make it through 3 supervised internships with professors and cooperating teachers; pass your district professional orientation plan (2 to 3 years) with principals and peers checking on you; and then not know the sun doesn't go around the planets. You also have a content supervisor, adopted curriculum, and possibly a content observation annually.

If that's the case, the teacher must not be a real certified science teacher or the district is the problem. In such a case, it would be possible to non-renew a teacher or demand an improvement plan in no more than one year. At the end of two year's you'd be gone or transferred or something. If the principal is incompetent, the district is stupid, and the teacher graduated from a non-accredited school and was credentialed by an alternative route (like TFA) it's possible, but still a very unusual situation.

Even with the shortage of STEM teachers putting pressure on districts to keep the bad ones, there is still an effort to fix problems or get rid of them.

I've taught in rural GA and SC (probably a lot like Mississippi), and I still didn't see protected teachers except political appointees (like the superintendent's in-laws) or coaches. Schools don't like the parents and public complaining so they will usually ask really bad teachers to resign or non-renew them or hassle them with improvement plans and transfers until they quit.
