Yes, I agree.
The argument of false imprisonment rests on preventing him from leaving, but is that a felony? I don’t know. It seems to me the ‘citizen’s arrest’ situation is unclear. The law says something to the effect ‘witness or have immediate knowledge’ and it is not known how the defendants found out about the trespass. Did they have a video feed, or access to one? Would they have to have seen it real time to claim ‘immediate knowledge?’
The suspect ran right in front of the father. The fact that the father was aware of previous burglaries from that house, as apparently every other neighbor in the neighborhood was aware of, would mean that the crime was committed within his knowledge. The fact that the suspect was fleeing at full speed when he was yelled at by the neighbor is more than enough probable cause that he was committing a burglary, especially in light of the prior burglaries.
