FFS this is getting overblown. It's not like the sea lion started chowing down on her and tempting the wild creature with bread or whatever it was they were throwing in the water is just asking for confrontation.
Oh yeah... sea lions are killers and attack people! Look out!
I work in Steveston and heard nothing about it yesterday. No buzz on the streets about it anyway.
Having worked up there for several years I've seen my share of ignorant people thinking it's fun to feed birds and mammals regardless of the numerous signs telling people not to.
Though I must admit that seeing people on several occasions buy French fries from take out windows then toss a few in the air for the gulls always made me chuckle. The two or so gulls would very quickly alert 20 others to swarm over for their share and freak the idiots out.

Then other people would get annoyed that the gulls would harass them while they dined outside. Well, duh!
