Something explosive is happening on Instagram these days. No, not just the newly added support for 15-second videos. No, not the new White House Instagram account. All of those developments pale in comparison to the official new Instagram account for the US Transportation Security Administration. Late last week, the "TSAblogteam" account began publishing photos of dangerous items the agency confiscated from travelers at airports across the country. Already, it has amassed pictures of all sorts banned items, from fireworks to loaded guns to grenades, even knifeguns. Armed with a hefty supply of hashtags ("The perfect #knife to bring to a #gunfight") and displaying a savvy use of photo filters, the TSA's Instagram feed puts most other users to shame, let alone other government and organizations' accounts.
