After four consecutive incidents, I don't think so. One or two incident could be said (for arguments sake) accident or rubbery. After 4 back to back incidents, anyone would say there is a problem. Why picking at Indian student for rubbery - The world knows that they are not from affluent compare to our AMERICAN BIG DADDY'S sons & daughters. Here a pattern is growing to aim at Indian Students. Barak Obama is even thinking of "outsourcing jobs". What kind of signal he is giving to people out there? My only request to the Presidential candidates that they better pay attention to these happenings. AND The Indian Government (is there any?) should reconsider signing the N-Deal with the US.
