I do not think the fact that he is legally dead means he could get away with a crime - it would be more like if someone who was not born in the United States, and therefore did not have a US birth certificate, committed a crime in the United States. The legal person who was declared dead could not be convicted of the crime, but the physical person could still be convicted of a crime and go to jail. This could also be similar to a corporation that commits a crime - corporations can still be convicted of crimes even though they are not living persons.
Late? Climbing wasn't recognized as a sport until the late 1880s, and 1910 was the year the carabiner and rappelling were invented, belay technique and climbing shoes were invented in the 1930s, and nylon rope wasn't invented until the 1940s - so whoever climbed it first didn't have any of those things, and did it without anything like modern protection or a good way to get down; I'd say they were crazy/ahead of there time, not late.
Also, the jump is 1.4 meters, and it looks well protected. I'd probably do it.
Aside from the ones that are simply correcting misspellings for words pronounced identically (sew vs sow, baited vs bated) these aren't generally true. While its true that myriad and plethora once had different connotations, those have fallen out of common use, so you aren't incorrect when you use them either way, because per common English, you are correct. Could care less is another one - its an idiomatic expression that makes use of figurative language to suggest the opposite of what it says literally. Virtually no non-native speaker would be confused by it. As for literally vs figuratively http://www.merriam-webster.com/video/0038-literally.htm (all their videos are awesome, by the way).
As for tough row to hoe (which is how I've heard it) speaking as someone who has hoed rows in a cornfield, hoeing a road would certainly be absurdly difficult, regardless of why anyone would actually want to do that (ancient greek punishment anyone?).
"Almost a standard deviation" can just as easily be rendered as "Less than a standard deviation." No mention of statistical significance, no link to the actual study. For an observational study like this, thats tantamount to meaningless.
