Judicial, i.e. the courts. What isn't judicial is law enforcement determining/imposing sentences on their own, at the scene of 'crime'.

One is a system of laws and justice.

The other, which you are arguing in defense of, is a police state with unchecked authority given to police/no system of balance.

What you are defending is an un-American policing system. Something more in line with the Judge Dredd comics (the point of which is that sort of thing is bad, in case you miss it).
