A first-person account from a blockader who accompanied Ramsey Sprague into the conference and documented the act in the above video:

“Early this morning, the PipeTech Americas Summit met at the Woodlands Marriot near Houston, Texas. Delegates from various pipeline construction corporations traveled to this venue to discuss the newest advancements in pipeline technology, how to facilitate a cozy relationship with regulatory agencies (a lesson given by the Army Corps of Engineers), and to give a collective pat on the back to this thriving ecocidal industry. Among the first scheduled speakers was Tom Hamilton, Manager of Quality and Compliance for TransCanada’s Keystone XL Pipeline, set to deliver a case study of the safety measures of the Gulf Coast Project, the name given to the southern segment currently under construction. Tar Sands Blockader Ramsey Sprague and I dressed to match the crowd and joined the audience.

Ten minutes into Hamilton’s time at the podium, Ramsey stood up and chained himself to the sound equipment positioned next to the projection screen, quickly delving into an impassioned speech on the irony of TransCanada lecturing others on safety and compliance. The audience sat silent, cameras aimed at this impromptu act, as security officials attempted to address the situation without having to clear the room. As Ramsey spoke against TransCanada’s horrific safety record, as well as its treatment of indigenous communities and others whose land and lives are being adversely affected by tar sands extraction, authorities escorted him out of the assembly and into police custody. After being detained by three Montgomery County sheriffs for documenting the act (and subsequent arrest), I was given a trespass warning and told to leave the property immediately.”

Ramsey was subsequently arrested, and if you're so inclined, you can contribute to his bail fund here.
