According to a story in today's Sydney (Australia) Morning Herald newspaper:
AN AUSTRALIAN family on a mercy dash to a dying relative in the United States were detained without food or water before being sent to a detention centre and forced to spend the night with criminal suspects. Their ordeal finished with them being deported.
This happen on January 13th and 14th, before Ohama became president. I hope changes have already been made so this sort of thing won't happen again. Treating famililes visiting the US with valid travel visas, passports and return tickets badly cannot possibly make us safer in any way. In fact it makes people hate us and makes it more likely that Americans will be treated badly when they travel overseas.
