I spend a lot of time in Galveston as we live 30 miles from the Island. I am in no way condoning what they did. Common sense would tell you that unless you live under a rock the current overall social climate would say don't do this. The officers should have used common sense, they did not.
But as we rush to judgement based on the initial pictures and reports, make sure you get all the facts. Even though it will not change opinions, or the visual shock of the situation at least it explains a few things. The procedure of handling people that have been arrested by a mounted officer is that they call for transport for the detainee. However if the transport is not available then there is an established procedure and as stupid as it sounds what they did was the procedure taught during mounted patrol training (I know stupid, but it the training). I know mounted police in both Houston and Galveston and it is part of their training. So these officers called for transport, but the dispatching supervisor denied transport because there was not a car available. The arrest was made literally 350 yards from the facility they were taking him to. If the officers used common sense one should have walked him there on foot. As far as a horse spooking, yes it can happen, hence the reason they are trained to drop the lead to the arrestee if it happens and never wrap it around your hand. So as people say they should be fired, well okay but they would be reinstated with back pay really quickly when they pointed to the procedure in their training manual. So the chief apoligized, committed to changing the training and the procedure and will counsal the officers.
Mistakes were made and they have committed to correcting them. Other circumstances are involved and again I am in no way saying they justified the situation in any way but here they are. The person they arrested should be going to a mental care facility, not to jail. He has done this before, he has been arrested before but for nothing major but more related to his mental condition. He fails to obey requests from police and basically was under the belief that he lived at a house there and refused to leave the yard and area. The owners had complained numerous times and the police had talked to him numerous times but he always returned.
I am not defending the officers actions but I would not want to be a policeman in Galveston. It is a party place and has become so expensive that most of the long time residents have had to move to the mainland to afford living in the area. Most of the houses are weekend only and in the older parts of the island where many of the minorities live in run down house, investors are buying properties for $30k and renovating them and selling them for $250K. You literally have the renovated house that a wealthy couple from Houston spend weekends in on the same street with house that are about to fall down. Literally the long time lower income residents are being pushed out of their neighborhoods. Police on the Island spend a lot of their time just listening to the complaints of the weekend residents, dealing with drunks, and crazy beach goers. The whole place is a recipe for disaster.
It is not a good situation overall.
