6 dudes invade a home? Sounds more like a gang going after some druggie to steal his stash.
What would six dudes otherwise invade for, a humongous TV? That couch in the basement? The fridge?
A lot of these losers work in, “Teams,” to inflict overwhelming force upon their victims.
Home invasion types now work in crews/groups. The idea is that their numbers will overawe any victims that happen to be home and reduce the time to grab the usual valuables. If nobody is home, they can more easily clean out the house in no time flat.
As for what they’re going for? Desktop and laptop computers (not just for the computer itself but for the data on it, which can sometimes be resold for far more than the hardware itself - and the computer itself could be thousands of dollars), phones, game consoles, certain pop culture collectables, home theater systems, firearms, ammunition, collectable sneakers (yes, shoes), easily fenced leather goods... All of which is more easily and rapidly stolen with multiple people.
FYI, they started doing this back in the 90s. Your perception of a home invasion crew only showing up to steal a druggie’s stash is decades out of date.
