In Texas a new policy has take effect which was brought forward by the Texas Department of Criminal Justice(TDCJ). What this policy does is that it prohibits Texas inmates from "maintaining active social media accounts for the purposes of soliciting, updating, or engaging other, through a third party or otherwise" 

 First off one of the main issues is that the inmates do not have internet, the only way they can communicate with their families is through letters and in person visits which the TDCJ monitors. The TDCJ wishes to salience inmates who continuously voice their opinions on a verdict or sentence while others use it as an outlet to discuss life behind bars, which helps prepare them to reenter society. One large impact that this policy has is that it also effects the First Amendment rights of people who are not in prison because they are worried that any social media sites or accounts will cause the TDCJ to discipline inmates under the new policy. The actual policy itself has been touted as vague because family members have been seeking clarification on the policy itself, families are unsure if a Facebook page or Instagram picture involving an inmate will cause to TDCJ to punish them. What the TDCJ has done here is basically suppressing the voices of inmates and their supporters, by doing so they will be free from public oversight which is necessary to hold the state accountable. Here is another key situation of where a state government believes that it can do what it wants and not have to worry about the constitution.
