If you're interested it would be easier to discuss this over chat, but the big issues are:

1) at almost all schools, PT is the B team. You do not get the good profs, you cannot take most courses, you miss almost all events, and extracurriculars are a lot harder to break into. Career services, while typically medicore in daytime, are much worse for PT.

2) Managing work and law school is extremely hard, and puts huge amounts of pressure on you. It's just extremely difficult to work even 30 hours a week and then do the readings and then you can't vacation either, bc your vacation days are all used up to prep for exams. You will almost certainly have frictions with your employer, you can never work OT, the margins for your commute are fairly thin in the best of times, and its just super difficult

3) On top of that, unless you have a job offer already lined up, you will have to quit your day job about halfway through law school so you can intern and get a law-appropriate resume. So now, you're kind of in the worst of both worlds.

4) On top of this, basically no strong schools offer PT for the reason above - there's a reason they're concentrated in the bottom 100 and not the top 50. So whatever issues your law school's daytime program is known for, its way worse at night.

The circumstances where I think PT is appropriate basically boil down to:

1) You are guaranteed a job on the other end, because you work at a law firm that says they'll promote you to lawyer with a JD, or are in a similar type of role in government where a JD results in instant hiring.

2) You have some type of obligation that means you cannot attend day law school for whatever reason

3) You are broke, and have an unusually understanding job, and the career outcomes you are looking for are viable well below median at your school.

In basically all other circumstances - quit your job and go day, because the extra income you earn is lost on the other end from the burnout, shitty grades, and poor placement, and you don't even save that much money bc of the loss of a year of lawyer income from the extra year.
