Discuss the potential danger of jumping in the water next to an orca and state that alleged incidents of attacks by orcas on humans were not confirmed.
It's pretty stupid to jump in the water next to an orca. You never know if it might startle them or just tick them off and all they have to do is grab a leg and drag a person down a few meters to end the encounter. However, when the few supposed incidents of attacks by orcas on humans are reviewed in detail, it turns out none were actual attacks. Either no contact actually occurred (just feared), or no orca was confirmed at the scene (just assumed).
