There are some huge differences between AL & BNP. In comparing BNP vs AL....
AL surmises one word....EVIL
BNP surmises one word ...Incompetent
BNP never violated & killed democry and take away people's voting right ( BNP gave CTG election right after its one-party election in 96).
AL has twice became fascist dictator and betrayed after being elected by the people. In BAKSAL-1 and BAKSAL-2.
With regards to terror, political violence, terder/chadabaji, corruption, AL last 6 years rule as surpassed any past rule by multiple times and in unprecedented way. Political violence, thuggery has always been in BD politics. But AL's has been the master and by far has supreme terror and criminal record. Starting from Rakkhi Bahini's rape, killing, looting to Logi Boitha and to today's Chatro League's terror reign put BNP/JP/Jamaat's combined terror record to shame. Even ChatroLegue's own workers are being killed by their fellow killers. All education institution have become their arms factory and in total occupation. No other org can stay there. Tender, dhokolbaji, chada baji in every market, bridge, bus terminal are norm of day. So, given that all BNP, jamaat and AL do terror politics, the scale and depth of AL's rampant criminalizing of every institutions is unprecedented and in the league of its own.
With regards to corruption, all party does corruption (even US's dem/republican). But its about the scale. Again AL seems to champion in this league as well surpassing any past record by 10000s times. Surely BNP did some corruptions. Till today, there is not a single case proven, in 7 years of in depth investigation of Tarek Zia. Surely Tarek's fired Mamun did corruption and rightly in jail as all corrupt ones should be in jail.
But BNP's corruption seems to be most confined in a few handful of individuals like Mamum, Falu, Nazmul Huda. The horrific thing is that AL's corruption is 9000000 times more in quantity and the number of people who are looting them. Even if we take AL's own declared holofnama into account, we see people like Hanif increased their wealth from 1-2 corer taka to 500-700 core taka. In average all AL-MPs have increased their wealth 100-200 times. Some say they did it by farming fish (koti poti motshojibi). Lets not forget the hori loot of state banks, BASIC, Sonali etc to the extent that 4000 crore taka looting seems insignificant to the FM Muhit (tax payer's money). Share market theft by AL businessmen were so bad that even govt's own investigation implicated them and FM Muthit admitting cannot catch the 'Raghob Bowal'. We saw how the black cat Surenjit not put in jail even after getting caught red handed. We saw how the Padma bridge thief Abul Hossain got 'HoliMan' certificate instead of put into jail. We saw how the govt did not even press charges to BASIC bank looter-in-chief. The list of AL looters are way to long and covers every city, municipality, district and village. The scope and depth are just mind boggling.
So, not to say that BNP did not do its share of corruption but equating BNP and AL are equating a village typical thief with Godfather Veto Corleone's top hit man Luca Brasi.
