There was wrongdoing on the part of LMSD, but if you read up on the family, it is not the first time they have been involved in lawsuits. They were looking for lawsuits because they needed the money - they had the largest delinquent residential electric bill that the electric company ever saw. They owed money to a lot of other folks too. The kid did not have permission to take the laptop home because the family did not pay the insurance fee - that is supposedly why LMSD turned on the tracking/camera (to locate the computer). The FBI found no evidence of criminal intent and cleared the folks at the school district.
Sorry to belabor this, as I'm interested in the original thread.
But LMSD LOST the lawsuit, so clearly there was a crime committed. His family's monetary issues have nothing to do with his privacy rights being violated, and I'm curious why you're linking the two.
I would certainly file a lawsuit if my son's school surreptitiously took pictures in in his bedroom with his school-issued computer, regardless of what they got on camera.
