I completely agree. Involuntary bailee in the UK is one of the nastier parts of the law (IMO) it penalises you for being a decent person and gives the power to the asshole. It’s ripe for abuse.
It's not nice to stick eyeballs under people's vestiments. It's not nice to put hands on a stranger. Bad faith actions can be responded to without malice but there is no need to be nice. Non consentual cameras in a private dwelling are never good faith.
And before I get called naive, courts do look very favorably upon defendants that are nice.
