90% of the seizures of drug patrols are invalid!

An early judicial source blew up a surprise of the heavy caliber: 90% of the drug seizures in the streets by patrols ended in innocence due to the invalidity of the arrest and search procedures.
But the source revealed in contrast that 90% and more of the CID’s investigations end in conviction, for the validity of the procedures that are taken only after obtaining permission from the Public Prosecution and follow the proper steps.
In response to the question about the reason for the increase in the verdicts of innocence in drug cases, the source said: Do not blame the courts, because they follow the legal procedures prescribed for them, if the procedures of control and search is invalid, how to condemn the defendant ?!
