I'm unaware of any "two minute" rule. If people are blocking public access to a public facility, then the police need to step in. I for one would be happy to go about my business and if someone gets too close, then I will look for an assault charge to be laid, and if it isn't, happy to do it myself - from arrest to laying of the information. You are entitled to your opinion, and I am entitled to mine. Getting real tired of this.
