After 2011 there have been several instances of "passengers gone wild" where one a-hole get's out of line and get's the crap knocked out of him by other pax because we are all scared. Cockpit's are secure, there is establashed protocol for crew and usually pleny of passengers that are not afraid of a 2-3" blade if they view it as a threat to confront.
Having said that I believe the september 11'th attack scenario would have been quite different giving the stress and fear the flying public has today. Not to mention the last line of defence, the pilots.
