Yes. You're showing something that is not racism but disparate outcomes based on arbitrary standards.

So most terrorists are Muslims. Charging more Muslims with terrorism does not signify racism of any sort. However, if you could find that the institutions standards for charging were different from different races, then yes you would have institutional racism. It would be racism by an institution. The weaksauce common usage of "institutional racism" on the internet is one where there isn't racism in the first place.
