Limestone County, Texas Arrest Records and Warrants
Despite having a relatively large population just over 22,000 as of the 2008 census report (which you can access for yourself at http://www.fedstats.gov/qf/states/48/48293.html), Limestone County has a rather low prisoner population of just 214 prisoners (as of the TDCJ report at http://www.tdcj.state.tx.us/documents/Statistical_Report_2010.pdf).
However, just because crime appears to be relatively low in Limestone County doesnt mean that you shouldnt be very careful when it comes to hiring new employees and babysitters. In fact, whenever you form any sort of new contact, it is highly advisable that you at least perform a cursory search to see where they stand legally.
