1) They issued indictments of official oppression against two people. I could hardly call that "multiple."
2) You are making it sound like the indictments came down solely because of interviews with supervisors, based on claims none of those arrested did anything wrong.
Trouble is, we cannot know that, unless either one of us were on that Grand Jury. Which is highly unlikely. So as far as why the indictments were handed down and exactly what was said, all you can do is speculate.
Did you know that the Houston City Council voted to spend your tax money to get the records of those arrested expunged?
Did you know I could give a flying fork because it is not even relevant to me, especially considering the fact the only reason why the charges were dropped in the first place is because the acting police chief requested it?
That was hardly the only reason. That was the formality that they went through to effectuate the process.
And the reason why I said "multiple" is because I believe each of these officers were indicted on five counts of official oppression. Ten indictments is definitely "multiple."
