Yes. There's so much stuff out there about his unpredictable temper that I couldn't be bothered to hunt it all out. When posters ask 'where's the proof' and expect others to do the searching for them, it gets a bit tiresome. Some people will excuse every single instance of OP's loss of control by either saying it's just 'media stories' or by offering some lame reason for his loss of temper. Either way, they won't accept OP was ever in the wrong!
BIB - The room change incident:
South African journalist and radio presenter David O'Sullivan chatted to Arnu Fourie at the London games. "He told me he had been forced to move out, because Oscar was constantly screaming in anger at people on the phone. I thought Fourie was joking and waited for him to smile. But he was serious. I was taken aback. I had never thought of Oscar behaving like that"

Of course, OP supporters will brush that under the carpet along with all the other evidence of OP's foul temper. But it doesn't change what most can see - that OP was a loose canon with a short fuse who thought he was more important than anyone else and demanded to be treated as such. It's pretty obvious that his family allowed him to go unchecked and thus enabled (and excused) his unacceptable behaviour. OP supporters pretty much do the same thing. At the end of it all, Reeva is dead, and she might not have been if OP had been held to account a long time ago.
