...."misunderstanding" I would definitely remove that word from your vocabulary and replace it with "accountability"
....next if you want to be a leo and you meet your states requirements go for it. Here in CA if you meet P.O.S.T. standards you have the opportunity to be hired. Each agency can ADD to those requirements. All agencies are different. Time and distance is very accurate advice. Like I said above lose that mindset of trying to validate YOUR bad decision. Learn to take accountability for your actions. Especially in this line of work.
