He is serious. It is total BS what you are assuming.
It is totally legal to follow people
Totally legal? Not necessarily so. It is not legal to stalk and spy on people, to create fear, to invade privacy. Sorry to disillusion, but it is not legal to do that.
GZ was not stalking. and him following TM was totally legal
I see it legal in the context of the watch program, and just as the dispatcher had suggested to Zimmerman when said "are you following him(?)", and GZ said yes, then next the dispatcher said "that we don't need you to do that sir". Now (imho) this was being said mainly for GZ's own protection in the situation, and in which GZ complied with afterwards when said OK.
The dispatcher with the assumption of course that GZ is the good guy for making the call in the first place, was worried about his safety when told him we don't need you to do that sir (follow Martin in the dark), otherwise instead of the dispatcher sighting some kind of law to GZ to not follow Martin because of that law, otherwise if he was saying this because of a law, then GZ would be breaking that law. This is what some would want it to appear as to be the case in all of this when the dispatcher said this to GZ " we don't need you to follow him sir", as it being based on some law in which he was using when said this.
So now it is the detractors opinion that the dispatcher at this point is now looking upon GZ as an iffy player who is breaking the law in the situation, instead of the dispatcher looking out for his safety in which was what the dispatch was doing all along when said this.
Now if he would have ignored the dispatcher telling him " we don't need you to do that sir", otherwise with silence, and the law would have shown up with Martin dead, and Zimmerman alive as the person who shot Martin dead, then Zimmerman would have a serious problem on his hands, but the fact that Martin replied to the dispatcher in compliance with the dispatchers alarming assessment of the situation, by him telling him that suggestion for his safety, places Zimmerman in a much better position for what would be found next in conjunction with everything that happened in testimony there of afterwards, because it makes sense as to how Zimmerman could have found himself facing an escalating situation after surveying the supposed suspect Martin that night, and Martin now knowing that he was being surveyed or looked upon by Zimmerman in a way in which he did not understand, so it became next a situation of grave confusion between the two, where as in the coming together of this confusion it unfortunately turns deadly within the dark of a stormy night for one of the people involved.
Now did Martin feel that he could take Zimmerman, for whom was following or surveying him in which he did not like, so he confronts Zimmerman in the thinking I am going to kick this creepy ass crackers butt for following me, but not knowing that the creepy ass cracker also had a gun because he was part of a neighborhood watch program ? If this is what Martin did or thought, then it should become a lesson learned by all in the future, that you don't come to a fight armed with nothing but your fist, when you ain't sure who this creepy ass cracker is in the fist place, and so if you could get yourself to safety and report that a creepy ass cracker was following you in the dark for no good reason, wouldn't that have been the best solution for Martin in the situation in hindsight now ? I have taken on some situations in my time in a foolish manor, and I was just fortunate that the one I was taking on did not have a gun, or I wouldn't be here today.
So what it comes down to, is if Zimmerman was within his legal right to survey the neighborhood under the watch program, and if he was within his legal means to be doing it in the way in which he was doing it, then he is in the clear, other than the fact of sadly allowing himself to be placed into a situation where a young man is dead now, and all because of his possible mistakes that were made upon his possible miss-identifying of Martin as a possible suspect in the problems that have been going on in the neighborhood lately in which are not proven he was linked to, and then Martin just being in the wrong place at the wrong time. Sadly it all added to the confusion due to the time of night that it was, the conditions of the night, the setting, the wearing of clothes that appear suspect, the walking and acting strangely that Zimmerman noticed as a watchman based on his supposed training I'm guessing, thus creating the perfect storm of confusion in which could even place a seasoned police officer in the same boat of miss-identifying a potential suspect in such a case, where as such conditions would make the police officer want to question the suspect as to where he is going maybe, and why he is out walking in such horrid conditions in a neighborhood plagued with crime ? It appears that what we have is the perfect storm of confusion in this whole tragic situation, and in such a situation people must know to keep their heads calm cool and collected or face the same possible results again and again, just as these types of scenarios sadly play out all over this nation in confusion there of, but it takes all to learn and keep themselves safe, and ultimately out of these perfect storms regardless of who it is that we may encounter or are dealing with at anytime in our lives.
Stay safe everybody and learn or educate yourselves, it is the only way forward in life.
