Although the Pot was found via the poisonous tree, & the taking of the Kids therein, the scales of Justice will weigh the right to privacy and the violation therein against the protection of a Child. The Protection of the Child (I fully believe) will carry more weight. This should not last long, since the potential "harmful" Pot has been removed, and the Police force can push for the release back to You in trade for not suing their fucking ass. Look up "Abuse of Power" on the net under Texas Penal Code. It is "DOCUMENTED" that they are guilty of such, a criminal offense, and a Civil Rights violation also. A formal complaint needs to be made the the DA's Office, then request to schedule a meet with the IAD, AND if You can get just ONE Civil Rights Atty. to call the DA's Office asking a few questions, that will put the heat on, because a multi-million dollar Civil Rights Action hits the Pocket book of all the City Employees, Police, DA & the CPS People. The avenue for Civil is 1983. Just stating keys words, IAD & 1983 gets peoples attention fast. They will NOT play nice until their ass is in a sling. IAD (Internal Affairs Division - Cops Hunters! ) meet is free, and a Civil Atty's call should be able to be made for around $100 bucks. It don't mater if He does or does not file on your behalf, you just need the threat made by asking innocent questions on your behalf. 3 avenues of attack beats one, trust me. Hope this helped.
