Also, in "this situation", they already have camera footage of it being one guy coming on his own.

3 burly overprotective brothers vs some creepy stalker dude who shows up late at night like a coward? Those are odds that I'd totally put on the brother's side. Since the cops had already "Sorry, not much we can do"ed the sister, I'd happily be big brothering up and taking that confrontational risk.

(I'd also happily do it with barley plausibly denial "sporting equipment" in hand as well - 3 burly Scottish brothers carrying cricket bats vs one cowardly late night creepy stalker? And if ever needed I'd try on the "Why yes officer, we were all on our way back to our sister's house from a late night cricket practice when we discovered a man interfering with our sister's car!" line.)
