"Terrorism is an invention through which any two armed people can take over an entire industry, namely television, with the eager cooperation of its owners."
Tv is a cool medium of which requires participation. If the audience (public) are not "put on" to terrorism, that is not participating, the the power of idea will cease (and the secondary effects like the issue raised here).
You can't have a hot war on a cool medium. Always a pleasure to meet another McLuhanite!
