We should require aspiring border patrol agents to undergo complete invasive searches as a part of their training before they are allowed to demand them for others.
I imagine the same kind of thing would be done if they had to go through invasive searches. The searches wouldn't match reality.
In an early episode of Star Trek Voyager, the emergency medical hologram subjects himself to a time-limited disease program ostensibly to better understand his biologc patients' suffering, but claims to do so to demonstrate that illness is no excuse for poor productivity. When the disease afflicts him for hours after the programmed end time, he freaks out. Later, his nurse tells him she extended the time, because "the worst part about pain is not knowing when it is going to end."
Perhaps the best way to match reality is to drug the aspiring officers, stash "contraband" inside one of them, then subject all of them to the same invasive searching until the "drugs" are found. The "smuggler" then has to spend an undetermined amount of time (~1 week) in a jail (not prison, jails are for temporary holding) cell under an assumed crime in another district, as to ensure the jailers treat him or her the same way as any other criminal.
TASERs kill a lot of people (more than one a week), but it's usually ostensibly not intentional.
I don't know what's up with that fourth result, though.
Real life might be repeated tasings with no one to support you as you fall onto tarmac.
Invasive searches, however, I fully agree with. Even at a lesser scale, standing there naked in front of your fellow workers getting your anus probed correctly is surely going to be memorable. I would fully support them using each other for training and proper procedure.
This particular post clearly points out that that this is common and that there is a pattern, which IMO points to management rather than officers being the root cause.
An officer should be thinking, "Wow I'm going to lose my job or face criminal charges if I do this search", not "Hmm I don't think this person is going to enjoy this search very much". And it's pretty obvious to me from the terrible epidemic of police brutality that this attitude is not common, nor encouraged.
Obviously you won't do anything that leaves actual lasting harm. Let's not get silly here.
edit: for the slow among us, obviously I don't believe this.
While it might clash with the "but they're proper human beings while those in jail are lesser humans" mentality some have [1], they should absolutely have a sense of what their punishments mean to people, and what the conditions where they sent them are.
[1] To which I have to say, I hope you get thrown in jail sometime, something lots of otherwise upstanding citizens get to experience at some point or another, and not always because they were guilty (or unethical/unjustified which is a different thing), and then we'll see if you'll change your tune about prisoners being some kind of subhumans deserving everything they get. Especially in the US, a jail-happy country with 5% of the world's population but 25% of its prisoners.
Even if they are only inside to get a taste, they will at least have "I get to go home after this" to hold on to while they are in.
