Should this teen have been jailed after urinating on a public war memorial?
A similar incident happened at our National War Memorial in Ottawa back in 2006. There was a large public outcry at the time and charges of mischief were laid then withdrawn by the Crown after some restitution, public apology and community service was done by the man prior to the charges being dropped. http://nathanr.ca/news/local/charge-dropped-for-man-who-urinated-on-national-war-memorial/ I think it all boils down to intent, myself and how aware he was of what he was doing.
