routine(ly) - of a commonplace or repetitous character.

It is important to keep in mind that lion attacks are still extremely rare in California and nationally. For some reason, humans worry much more about rare dangers than about common dangers. For example, in California, from 1986 through 1998, exactly two people died from mountain lion attacks, whereas in one year alone, over 4,000 people died in traffic accidents, including 800 pedestrians. So we should be much more worried about meeting a dangerous car rather than a dangerous lion, but we aren't, because we are much more familiar with being in a car than we are with being around an uncaged mountain lion. Rationally, if one avoids hiking because of fear of mountain lions, one should also avoid driving in a car, or crossing a street as a pedestrian.

In this case, it probably would have been possible to clear the area, sedate the the big cat with a tranquilizer dart, and transport the animal to a more remote area.

Urban sprawl in California - and elsewhere - helps to displace animals such as cougar and coyote from areas that had previously been relatively remote. Coyotes now prowl suburban areas after dark and help themselves to Fido and Sylvester, and cougars may instinctively stalk - and attack - unfortunate joggers and bicyclists who pass through areas where the big cats prowl.

Nevertheless, I think it's likely that far more people in the United States die each year from insect bites and stings than from cougar attacks. Also, most big cats are instinctively wary of humans and will avoid us.
