I was taught the same thing and we are teaching our kids that as well.I was taught never to go near anyone who was following me, we did not have 911 or cell phone then.My kids were taught by me and school to never go near someone following you, get to a phone and call 911.Now the school is teaching my grandson who is 6 the same thing.My
10yr old same thing and she carries a cell phone.IMO It bothers me neither did. I know it most likely would not have changed the outcome but IMO that is something we will never know because a call was not made.IMO That is why 911 is here for us IMO.
HOWEVER, I was also taught never to follow anyone that I felt may pose a threat.
Sure a 911 call was made, but the person that called chose to take the law into his own hands anyway. It's not Trayvon's fault that he didn't call 911 before he was killed. Perhaps he was running to get indoors where he felt safe so he could call 911 and report a suspicious man had just been following him.
