well if the definition of probable cause is "a reasonable belief that a person has committed a crime" then I don't think it's unreasonable for somebody to believe that a top pro bodybuilder has committed a crime.
Why? Because he is a bber? In the states that is a lawsuit, you don't stop somebody based on you think they are a criminal...
For instance, I have been stopped for "driving while black", basically profiling...it's annoying....
But, a cop cannot stop and arrest you for no probable cause, meaning that there has to be a legit reason (license suspended, taillights out, etc)
being a bber, is not a crime, And making him submit to a blood test is beyond unreasonable...he admitting to smoking weed in another country, not there, he had it and steriods in his system, but he wasn't under the influence of weed, so he wasn't high, which I'm guessing would be a crime.
As someone had said, they were usig him as an example...
