We would love to attend this meeting to show our support but are too paranoid. I'm sure a news crew will be there with cameras for all to see. We don't want our employers or some family members seeing us on TV. We can't take the risk.

Are there any alternative ways to show our support?
I certainly understand your concerns. If your employer somehow sees you on TV advocating mmj, and subsequently takes an adverse employment action against you because of your opinion and/or medical situation, your employer can be liable for retaliation and discrimination. You are exercising your First Amendment rights to speak. Since it is a city council meeting, you have to be present to be heard....may have to get on the agenda though.

Nonetheless, the fact that you (and probably others) are afraid to speak out further enables and reinforces the prejudices that abound.

Hopefully, there will be mmj representatives/organizations at this meeting, like Sensible Colorado, who will speak on behalf of the many. Contacting them may be an indirect way to get involved.
