More E = K
It's also worth remembering that there's not much that's new under the sun. According to Williamson, E = K. Assuming that 'knows' is factive, we get E --> T. There was a time when some thought that Gettier's examples were defective because they assumed the principle that someone can be justified in accepting a proposition, h, on evidence p even if p is false. Clearly, the thought was that evidence can justify only if it consists of true propositions. The problem with this, as Feldman pointed out long ago in his, "An Alleged Defect in Gettier-Counter Examples" is that even if the principle is true, there are still counterexamples to the JTB analysis. He gives examples in which there's a justified belief that is true, that doesn't constitute knowledge, and that doesn't derive from a false belief.
