There are currently a lot of quotes about "hundreds of injured people" during the Catalan independence referendum but they all come from a potentially biased source, (Catalan government), and don't mention the types of injuries sustained by the protesters.
Are there detailed statistics somewhere from a less partial source on how many people were seriously injured and required medical attention?
A lot of the arguments against the Spanish government rest upon the unreasonable use of violence, but it's hard to judge the scale of this violence objectively.
Note: this is on-topic for Politics.SE because the issue has become a core point of discussion in the current Catalonian independence movement.
