TORONTO, Nov 25 (Reuters) - Canadian Prime Minister Justin Trudeau on Friday defended invoking emergency powers to end anti-government protests that paralyzed the capital earlier this year, citing the threat of violence and lack of a credible plan by police.The "Freedom Convoy" demonstrations against public health measures including vaccine mandates shut down Ottawa and blocked some border crossings for weeks in January and February.Lawyers for the convoy organizers and others said Trudeau had not read a plan prepared by Ottawa Police and pointed to one border blockade being cleared and criminal charges laid at another without the use of emergency powers."We kept hearing there was a plan.... (but it) was not even in the most generous of characterizations a plan," Trudeau said.It allowed financial institutions to temporarily freeze the bank accounts of people believed to be supporting the convoy and allowed the government to order towing services to clear blockades."
