New questions from the duplicate thread you started today:
"Will I face criminal charges ?"
No way for us to predict this intelligently.
"If the cops were already there wouldn’t they have already arrested me?"
Unlikely that a custodial arrest would be made for a shoplifting charge.
"Also I just received a letter in the mail stating: 'This is a demand that you pay $206.95 in satisfaction of this civil claim. This is not an attempt to settle a debt...You have a right contest your liability in court.' Do I have to pay this"
No.
"what will happen if I don’t?"
You might get sued in small claims court.
"I am 18 but my parents don’t know this happened and I don’t want them to find another letter like this in the mail. Should I just pay it?"
That's not for anyone here to say.
"How many of these letters should I expect?"
Only someone familiar with the loss prevention policies and practices of your victim will be able to provide a reliable answer to this question.
