Linebarger Goggan Blair & Sampson, LLP Questionable Letter, about a ticket that I got, they are requiring payment for!!! San Antonio, Texas

I actually did get a speeding ticket a long time ago that I tried to resolve but was unsuccessful. I received this letter from this law firm on about 02/19/2013, and initially I believed it cause it had my DL# on it and it looked very convincing. But after I thought about it and looked into it a little more, I realized that the local police department wouldn't hire a law firm to handle this, they would simply send out a warrant and lock me up for it. Not only that, the amount that the law firm is requiring is a substantially larger amount than I owe the local PD. So there is a lot of red flags being thrown up here, and apparently there is a lot of others facing this same exact situation. So I am going to continue to look into this, but if anyone has any comments about it then please get back to me about it. I really appreciate it.
