It is quite difficult actually, if only for political reasons. Taxi drivers have a high level of nuisance, which gives them bargaining power. It would be suicidal for the gvt/institutions to go directly against them. While violence is unacceptable (and hopefully the perpetrators will be found and tried), one also needs to realize that taxi drivers had to pay a high price to become taxi drivers. The current price for a license is 250000 euros in Paris (according to http://fr.wikipedia.org/wiki/Taxis_parisiens http://fr.wikipedia.org/wiki/Taxis_parisiens). Anybody in that situation would be pissed, and a fairer solution would most likely involve a plan to rebuy licenses.
