Exactly why does it matter one bit how much he weighed?
Exactly how did his apparent suspension from school contribute to his killer's actions?
Exactly what does it matter if there were a number of burglaries in the community --- was Martin breaking in to a home? Was he peeping through a window? No. He wasn't. He was walking the sidewalk after buying candy.
Recent crimes committed by other blacks in other locales are just that -- crimes committed people other than Martin. They have absolutely nothing to do with Martin --- unless one wants to argue that he just paid the price for crimes that people who share his skin color committed.
The only thing Martin was guilty of was being black in Zimmerman's neighborhood. That's why he's dead. The rest is just bullshit.
