Well, the way I see it and I'm quite certain many others do as well, is its a really "poor" thing for a parent to have killed their child.. Poor to say the least..yet, we know parents unfortunately do kill their kids..
So, in looking at the fact that in this particular scenario that was commented on regarding the alibi that in your opinion is "poor"..we aren't exactly talking about someone with a really great, level head here who makes well thought out decisions.. In this scenario we are speaking of an alibi for the crime of having killed their very own child..
So, for me the fact that their alibi may be "poor" would be no surprise.. IMO someone who has killed their child and the murder was in no way premeditated, but rather was a series of events that led to an escalation of tension, anger, frustration, and resentment that all came to a head and resulted in their killing their child..
IMO I personally would not expect in that scenario for the perpetrator to have a very thorough and well thought plan of how to cover all the bases after the fact of having killed their child... In fact I personally would expect just that, a "poor" alibi to have been constructed in the aftermath of having killed their child..
In many theories this was not a premeditated murder so to speak, but rather just as I described above an escalation of extreme anger, frustration, and resentment culminating in his lashing out on a totally innocent, defenseless, very small framed young man who died as a result..
"Poor" anger management skills, "poor" self restraint, "poor" coping skills, etc, etc..as IMO the list truly goes on and on of what all issues are at play that all are of a "poor" grade..
My opinion is it that the "poor" alibi you speak of fits perfectly with all of the multitude of other "poor" issues, mindsets, skills, etc that are at play in this crime with Mark Redwine.
As always jmo *IF* Mark Redwine is in fact responsible for having killed his son.
