I've definitely had big friends in the past who were always getting shit started with them, even just walking down the street between bars in a group they'd out of nowhere have a stranger single them out, shoulder them while walking past, and voila now there's a street fight.

But that's rather different, it's more about sport than crime. Half the time they'd become drinking buddies afterwards.

When desperate people are on the prowl for people to rob however, I don't believe it's typical for them to prefer tougher targets. My understanding is most thefts are opportunistic and unattended, which tells me there's obviously a preference for less resistance, not more.
