Thanks a lot @milano1113. They would have treated him as a witness if they had any intention of actually prosecuting the crime. They didn't. All they were interested in was taking in as many people as possible. Contrary to what you may have been told, bail is not free at least not in Kevin's country. So to be bailed, some money would have to be paid and it is unrefundable.

Yes, everyone who has been in Kevin's situation always ensure that they don't go through it again.
