You may run into a situation where a jail employee refuses to give you the information you requested. Don’t get angry at him, he’s probably just following policy. If you feel you have a right to the information you can always file an open records request. The main things to remember are that the request must be in writing and the information requested must already exist.
Don’t expect to slap down a piece of paper and that they will give you everything you want. There are time frames and guidelines that apply under the Public Information Act. I will tell you now that jail employees are NOT knowledgeable about open records requests. One of my researchers ran into a lot of opposition and rudeness when she was trying to find out who to direct an open records request letter to.
You can mail your request to Central Records. You can email your requests to Record@bexar.org. Or you can go in person, write down what you need and hand it to them. Records was the section that got us on the right track without being threatened by our request. Before you make your request I strongly suggest you view the P.I.A. training video that the Attorney General has on his website. Once on the page you will have to scroll down to find the video.
