Jailed activist and political leader Akhil Gogoi was at his thundering best as a posse of policemen dragged and shoved him inside the Assembly to prevent him from speaking to the waiting media on Friday morning. Gogoi arrived at the assembly to take oath as MLA for the first time. All MLAs took oath on the first day of three-day assembly session -- the first of the 15th Assam assembly -- which began on Friday.
