Kizzy, when I first researched Armstrong, I, too, thought the Wikepedia page on him had to be accurate.  It isn't, and Wikipedia is not always trustworthy.  Armstrong made some powerful enemies, and found himself railroaded in NYC, where he found that the big bankers pretty much rule the day.  He was put in prison for contempt of court and then kept there illegally for years.  May I suggest you watch this trailer on a movie about him, and then perhaps watch the movie itself.  It has to be ordered on line, because the powers that be make sure it doesn't play in America.
