I would never upload my DNA profile, but I have relatives who do. So I am not broadcasting the info, but other family members may.

I am generally alright with law enforcement using public information like this, but it could be used against me without me ever making said data public. So I find your argument invalid.

So lets say the police see your brother, and realize he looks suspiciously like a criminal they are looking for, so they come find you.

Your argument is that your brother's appearance can be used against you without you ever going outside, so it should be illegal for the police to look at people.
