Sorry, but I think US law enforcement is way out of control here:
"arrested and handcuffed while dropping her daughter off at school"
"handcuffing, stripping and cavity searches, swabbing"
"kept in a cell with drug addicts"
"posting $250,000 bail"
"despite my incessant assertions of immunity"
So she is being treated like a dangerous criminal, her personal privacy violated (because of course a foreign diplomat will hide weapons in her vagina when driving her kids to school, can't take any risks there), and bail is set at a quarter million dollars. For what? Because she allegedly filed incorrect paperwork for her housekeeper. Of course, if there's a reasonable suspicion of fraud that should be investigated, but why the big show of force?
What was wrong with just sending two officers to her house and delivering a warrant for her arrest? Also, even if the State department decided that she doesn't have full immunity, it might make sense to wait until a court confirms that interpretation before submitting her to a full-body search and throwing her in jail.
By the way, when did cavity searches somehow become a "standard procedure" in the way the US treats anyone accused of any form of illegal activity?
