Why does he owe anything to anyone? If I had been there, I might want to talk to others who had also been there, but I would not be going on any media radio, talk show, newspaper, etc. If someone wants to judge me for that, so be it. I would expect it was very traumatic for all, and appreciate any witness accounts, but I would not put too much weight into them as witness stories will vary and may not always be accurate. How one reacts to stress and anxiety, the ability to think quickly or not, degree of mobility. all will be a factor.
Personally, I find it appalling that JC is in any way being picked apart. he is NOT A SUSPECT in anything that LE has released (that I have seen or been directed to) and it seems to me we should not be accusatory in any discussion about him. But thats just my own opinion. We are all entitled to believe differently .... but hopefully, logically.
