Yes, it's called a Suspicious Person and police get calls like that all the time. I know because I listen to my police scanner frequently.<quoted text>
Why are you calling Martin a 'suspect'?
Had he broken any laws?
According to Zimmerman, he witnessed a person walking around at night in the rain aimlessly in a hoodie. Yes, that's suspicious. Zim also stated he didn't recognize the individual as resident there. He was correct. He stated Martin was acting "high or something" again, THC was found in Martin's blood.
Seems Zim was correct on all counts. Very observant for not being a police officer.
