Now it's argued that this power presents no danger in the hands of those who have used it responsibly. But as to whether or not the networks have abused the power they enjoy, let us call as our first witness, former Vice President Humphrey and the city of Chicago. According to Theodore White, television's intercutting of the film from the streets of Chicago with the "current proceedings on the floor of the convention created the most striking and false political picture of 1968 -- the nomination of a man for the American Presidency by the brutalityand violence of merciless police."If we are to believe a recent report of the House of Representative Commerce Committee, then television's presentation of the violence in the streets worked an injustice on thereputation of the Chicago police. According to the committee findings, one network inparticular presented, and I quote, a one-sided picture which in large measure exonerates the demonstrators and protestors. Film of provocations of police that was available never saw the light of day, while the film of a police response which the protestors provoked was shown to millions.Gresham's Law seems to be operating in the network news. Bad news drives out good news. The irrational is more controversial than the rational. Concurrence can no longer competewith dissent.
