Such as domestic violence enforcement, where as an officer you are commanded to protect the complaining party and to make an arrest if an assault has occurred. The problem with the execution of this law and the legal duties/liabilities to the individual officer or agency is that in the particular case of Domestic Violence you end up being forced to arrest people on "good faith" rather than "probable cause", knowing full well the arrest was invalid but having to do it anyways so you don't get in trouble. In doing so you imprison an American without just cause. Many times suspects charges are dropped at arraignment due to their not being any Probable Cause. Yet the officer and agency are protected from lawsuit, even though they knowingly violated someone's rights. In this case the state has decided that protecting life is more important than the constitution and individual rights.
DUI checkpoints, WDFW checkpoints. These are unconstitutional and a direct violation of your search and seizure rights. Why do we allow law enforcement to force administrative searches on us where they are seeking to incriminate us, under the rouse of " protecting the community".
Here is a tip if you ever get pulled over for DUI. Never answer questions, never participate in field sobriety tests, never blow on the PBT, "portable breath test." Anything so say WILL be used against you, the SFST's "standardized field sobriety tests", have only one purpose,,,, to incriminate you, so I would advise you to not do them even if you are sober. Blowing on the BAC is your choice, if you don't and are convicted you lose your license. Most DUI's achieve probable cause from the comments of the pulled over driver, PBT and SFST's, in most cases the driving alone is not enough for conviction, unless the driver is shat faced.
