This was all covered in the series two finale itself.
Mycroft may very well have the resources to cover the vantage points of a very specific location for a brief period of time but this does not extend to offering complete protection for every second of every day. As Moriarty lays out in the episode itself his network is under orders to continue until Sherlock is dead. Not just those individuals currently in London targeting Watson and co. but his entire network. There are just two things that can change that – either Moriarty himself will call them off (which is why he kills himself to stop this from happening) or Sherlock has to die. Sherlock has to jump because as long as he's still alive those closest to him are the targets of Moriarty. This is also why he can't resurface as alive again until he has dismantled Moriarty's network and the reason he can't reach out to Watson and tell him that he's still alive, for fear that Moriarty's network will still be monitoring him (Watson) and thus putting everyone back in danger again.
When you think about it this actually dovetails rather nicely with the series three finale.
In series two Sherlock 'kills himself' to protect those closest to him. In series three Sherlock commits murder to protect those closest to him.

That he was trying to kill him in earlier episodes is irrelevant to my point, which was that it is possible to come up with a plot where the 'hero' uses brute force/violence to kill a very smart villain, but still do it in a clever way that involves psychology, cunning, technology etc. Rather than just pulling out a weapon that he shouldn't logically have had access to.
"That it was Sherlock's last desperate move."
It was Walt's last desperate move too.”
It isn't irrelevant that he tried to kill him in previous episodes though. You need the earlier attempts along with the mountain of other plot developments and set up that come before it to push Walt and several other characters to that point.
Additionally I'd point out that I think you're missing the point of what they were trying to do in Sherlock.
The idea here is that its not supposed to be a clever way of killing him. Unlike Walt's killing of Gus in Breaking Bad you aren't supposed to view Sherlock's killing of Magnusson as planned. It wasn't Sherlock's plan all along to get there and shoot him. This was his last desperate action because he had no clever plan. He had no other options. All that was left open to him was brute force. Imposing a clever death to make it a bit cooler would completely undermine what they were trying to do with the story and the characters.
As I said previously I think the problem with the episode was that they didn't do enough to show Sherlock's plan unraveling and to illustrate his desperation in having no other option. Of not being able to think his way out of the situation. Although I think Cumberbatch actually does a rather brilliant job of portraying that it might have been nice to have a explicit demonstration of it. Perhaps him running alternative scenarios in his head that all fail or something.
