The criminal is clearly the issue here and needs to be off the streets. Crime is bad and shouldn't exist.

It's also the individual's responsibility to protect themselves and mitigate risk, since this is not a perfect fucking world, and crime exists. That includes being wary of displaying items of wealth in public spaces.

Both can be true. It's not an either/or. And it is not victim blaming to advocate exercising caution. We don't live in a fucking utopia.
