Hollywood actor Wesley Snipes has been sentenced to three years in prison for failing to file tax returns.The star of the Blade movies got the maximum sentence available under the law, which US prosecutors had recommended.He was found guilty in February of failing to file federal income tax returns for 1999-2001.Snipes was acquitted on two felony charges of filing false claims and fraud in seeking millions of dollars of refunds in other tax years.But prosecutors urged the court to make an example of the actor in a bid to deter others.Snipes' lawyers said he was only convicted only of three misdemeanors and the US government's tax loss amounted to less than $400,000.
