By making it appear, and actually, much harder. More surveillance, more body guards, stronger loyalty checks can get you a lot of security.

And let's be honest. Who would take a bullet for this CEO of one of the most despised corporations in USA (that's saying something).

I honestly think, that the general distaste for this particular industry, is why the law enforcement had such a hard time catching him.

I did say almost. Putin is kind of the extreme example.

If someone is willing to live like an absolute hermit in basically a police state, hiding behind layers and layers of security apparatus, engaging lookalikes and only allowing the loyalty-tested anywhere near him, survival odds improve quite a bit.

But for anyone trying to live anything remotely approaching a normal life, or with any real freedom, your continued survival is completely due to the fact that the overwhelming majority of people in your world have a personal breaker against murder.
