of those involved here. anna, i want to ask you about this hashtag that has been going around called i ll ride with you. here s what some of the people there are tweeting. one says without a doubt i ll ride with you. but not just tomorrow. someone you else says if you need religious attire and needs to get from west adelaide s suburbs to the city on tuesday but don t want to travel alone i ll ride with you. because together the journey i ll ride with you because together the journey is more than fun. that friend is our victory, one haters will never know. tell us about this hashtag. reporter: yeah. quite amazing. it took on a life of its own yesterday as the siege was still unfolding. basically this is about australians showing their support for the muslim community. there is real concern obviously that there could be some sort of backlash, religious backlash, political backlash, because this gunman, this lone wolf, this 50-year-old man from iran decided to come out publicly
