I don't have the EM1, considering it but waiting for the goodies of the EM52 to land in an EM1ii.
but meanwhile, a protest march isn't exactly a fast moving subject, is it?..
So, are you making the most use of your EM1's AF abilities?
Perhaps this link can be of some assistance:

If anything, EM1 should do reasonably well to AF the initial shot.
I think the key was that it wasn't in daylight. Also, it was a protest but that doesn't mean people were moving in a slow march; it was fairly hectic with people running around as the cops threw flashbangs and some tear gas cannisters after some officers were injured.
I've used the E-M1 tracking quite a bit before and while I've never been impressed by it, it's certainly useable in a pinch (especially after the 3.0 firmware update) but I'd take a T3i over the E-M1 or X-T1 for tracking. I saw that mirrorless shootout video when it first came out and I always thought it was very telling that they didn't give any kind of hit rate numbers, based on my experience with both the E-M1 and X-T1 I would strongly suspect that the hit rates were significantly lower for the mirrorless cameras than the D4s.

WHAT are you talking about re inability to use in sunlight?!?
That's a PnS complaint. If you've only ever tried a cheap ML with no EVF then that's not a very valid opinion.
No, he's right. The X-T1 is far and away the best EVF for use in bright sunlight, but this has more to do with the terrible eyecups used by Olympus and Sony than anything intrinsic to the EVF.

Any decent ML body with a good EVF is not significantly different from using a DSLR.
FWIW, my XT1's EVF is particularly pleasant to use and I was using it to MF a slow lens in low light the other night, VERY low light. This was nearly impossible to do with the DSLRs we had available. (nearly full moon, the only source of light but obscured by cloud)
DSLR AF did not function on low contrast subject and MF was not working well with the optical viewfinder either.
We had to indirectly MF the DSLRs but I could just manually focus the XT1 via the EVF.
The idea that current EVFs are not significantly different from OVFs is going to be strongly colored by your intended use. For general use I completely agree with you (especially for the X-T1, they really nailed the EVF), but for applications with heavy using of continuous shooting, especially in low light, EVFs are very far behind OVFs.
Also, FWIW, the live view focus on my Canon DSLRs outperforms all of my mirrorless bodies in extremely low light as long as you're not in a rush. I agree that the EVF is helpful here, but it can be pretty hard to accurately focus even with the EVF as the noise makes it difficult to distinguish critical focus. It seems like when these kinds of discussions come up, people seem to forget that DSLRs also have live view.

Next time I'll have to remember to bring my low light DSLR focus accessory tricks just to speed things up but this was a great example of how good the XT1's EVF system is.
And if you have 2 functional eyes, whatever lag some EVF systems may have is also a non-issue.
I'd say the optical viewfinder is already obsolete, however simple, convenient and low-battery-power it is.
I would strongly disagree with this. The blackout period and slideshow behavior of mirrorless cameras EVFs in continuous shooting mode makes them almost useless for tracking action when there is a high degree of unpredictability. They may seem ok when you're doing something easy like tracking a person running straight towards you but when you have subject rapidly changing directions using current gen EVFs in continuous shooting mode is an exercise in futility.
