It doesn't seem to me like he has an agenda. Keep in mind that the "duck boats" are pretty much universally reviled by natives in Philadelphia; they are loud, feel out of place in the neighborhoods they operate in and are full of gawking tourists.

The incident in 2010 he mentioned was pretty big news in Philly. Just seems like a concerned reporter who was at the right place at the right time and noticed a series of recurring events with these boats.
