rules aim to deter lawless conduct by police and prosecution and often operate at the expense of placing probative evidence before juries for the purpose of arriving at truthful decisions about guilt or innocence); Thompson v. State, 123 S.W.3d 781, 784-85 (Tex.App.-Houston [14th Dist.] 2003, pet. ref’d) (unlike a criminal trial, a Chapter 64 proceeding is an independent, collateral inquiry into the validity of the conviction). 26 . Prible v. State, 245 S.W.3d 466, 469 (Tex.Crim.App.2008). See, e.g., Ex parte Mines, 26 S.W.3d 910, 914 (Tex.Crim.App.2000) (criminal defendant enjoys a presumption of innocence and a constitutional right to be present at a pretrial or trial hearing; applicant for post-conviction writ of habeas corpus enjoys neither); Dix & Dawson, supra, note 9, § 45.181 (<HOLDING>). 27 . Rivera v. State, 89 S.W.3d 55, 58-59
recognizing that this court in prible made it clear that a convicted persons effort to secure testing to show that another person was involved in the offense involved no constitutional considerations holding that a sentencing court did not abuse its discretion in departing from the guidelines range when the record supported the courts conclusion that the defendant was a danger to the community because he had been convicted of a crime that involved a threat against another person holding that the application of the enhancement for using a firearm in connection with another felony offense is proper only if there is a clear connection between the firearm that was used in the other offense and the one that was used in the offense of conviction holding that a statute imposing a one dollar court cost for law enforcement on every person convicted of a crime was not a violation of the separation of powers doctrine because it is reasonable that one convicted of a crime should be made to share in the improvement of agencies that society has had to employ in defense against the very acts for which he has been convicted holding that congress intent in  841b was to ramp up the punishment based on the type and amount of drug involved in the offense
