1. Making an illegal stop.
An officer needs reasonable suspicion that a law has been broken to
pull you over. Many stops are made without legal reasonable
suspicion, i.e. no violation of the law, which allows any evidence
obtained from the illegal stop to be kept out of court.
2. Failing to properly
administer field sobriety tests.
Officers are trained according to the National Highway Traffic
Safety Administration standards how to properly administer these
tests. But, because there are many steps in properly applying the
tests, many officers fail to learn to administer them properly or
forget their training and wrongly arrest the driver based on
scientifically invalid test results. This means there is no basis
for “probable cause” that a person is driving while intoxicated, and
the sobriety test results could be kept out of court.
3. Failing to properly
administer breath tests.
Texas law regulates the application of breath testing to DWI
suspects, and many officers simply fail to follow this law. Such
failure could cause the results to be kept out of court.
4. Not preparing for the ALR
hearing, suppression hearing, or trial.
Officers who are busy on the streets do not often have the time to
prepare properly as a witness in their case. In fact, many meet with
the prosecutor one time before trial. This could cause them to not
be prepared to explain mistakes they have made during your arrest.
5. Failing to properly provide
and maintain evidence.
Videos and affidavits get lost, affidavits are filled out at the
wrong time or improperly, and many other mistakes can be made along
the way concerning the evidentiary trail the state needs to prove up
at the ALR hearing, the suppression hearing, or trial. Police
departments are busy entities and paperwork etc. gets lost.
