Because judges usually need the support of the prosecutor and police to get re-elected. So the warrant will be issued, otherwise the judge is "soft on crime". It's never "the judge is strong on Constitutional rights."

You’re not wrong, but that reality didn’t stop a warrant from being issued or those envelopes from being opened

Nothing stops police from intervening in any way shape or form. The only thing a warrant does is make the actions or evidence legal for future legal proceedings .

Those dogs all operate on signaling from the handling officer.

If there is a long pattern of dogs are signaling "drugs" (irrespective of why they're signaling) when there are no drugs found, that sounds like a great angle defense attorneys can use to get any evidence found thrown out of court.

Interfering with the US mail is a federal crime. Further, even in states that have banned medicated abortions; both medications have perfectly valid uses outside of abortion (including things not related specifically to women's health altogether.) Neither the USPS nor the cop can know if the drugs are for illegal purposes without filing subpoenas and warrants for that medical information; and probable cause is going to be difficult to get, considering.

It's also a federal crime to interfere with interstate commerce, which is solely the province of the federal government to regulate. Additionally, USPS screen for illegal substances anyway; maybe not every package, but enough to suggest that there shouldn't be local bastards screening them too.

Edit to add: Screwdrivers are commonly used tools for breaking in, they’re way more useful than lockpick sets, for example, and they can be used as a weapon, too.

Possessing a screwdriver, or even carrying one, is not suspicious or illegal. It wouldn’t give a cop probable cause. For that they need other things; this is similar. Having a medication is not sufficient for suspicion. Even having been pregnant is not suspicious; since they’re also used to manage a pregnancy that has failed for other reasons.

In short these asshats need to stop being asshats.

Dogs "alerting" has as much grounding in truth as a polygraph test.

Polygraph results are not admissable in court, FYI.

We need an rct where the clinic sends abortion pills to some people and placebo pills to others. Or even to the same person in separate identical packages. Then see if the dogs alert more on the abortion pills or not.
