How does high frequency differ from computerized trading?  There are
plenty of unknown companies (such as the company RGM Partners, Ltd.,
here in Austin, TX) who specialize in "high frequency" computerized
trading quite successfully and who are looking to engage every liquid
market on the planet.

The remarks cited do not really tell us how computerized trading can
be dangerous, and what "improper trades" really are.  It's clear that
unfair access is a problem, but that doesn't say how computer trading
per se is bad.
======================================
Right. It's not the computerized trading which is at issue, but the extra
access to market information which the exchanges sell to investment firms
who set up their servers nearby. Chuck Schumer complained to SEC chairperson
Mary Shapiro in July that "for a fee, the exchange will 'flash' information
about buy and sell orders for just a few fractions of a second before the
information is made publicly available. These traders, using super-fast
computers, can then act on that early information to trade ahead of the
pending orders." The SEC has since proposed banning the practice.
Apparently, a SEC rule requires that a full second elapse before the
exchanges can make trades public.
