This week on Law Talk, the professors (ably herded by Troy Senik) talk about collusion -- what it is, what it isn't, who's in danger and who isn't. Then, activist judges make things for the Trump administration's travel ban and Richard and John explain why. Also on the docket: gun laws in California are amongst the toughest in the country. Does the Heller decision give the state more leeway in regulating guns even more? And we re-visit the Supreme Court's ruling on The Slants (and the Washington Redskins) and, yes, that famous selfie-taking monkey.

Have a banana, @ejhill.
