Most TV news
magazines have
struggled to attract
and keep audiences
in the past few
years.
To Catch a
Predator,
however, does well.
It's important to
have a fire wall
between reporters
and law enforcement
officials, said
Thomas Donaldson,
professor of ethics
at The Wharton
School of the
University of
Pennsylvania.
"Otherwise you have
media companies
making money by
supposedly bringing
people to justice."
