Sustainable democracy offers a practical sketch map for intellectual development and political maturity. Besides, sustainable democracy ensures reliable governance and democratic issue base confrontation of challenges affecting the citizens from insecurity, social justice, and respect of human rights. Reflectively, sustainable democracy, as a concept of institutional approach in reforms, offers a solution based management of government institutions. The government of Bangladesh remains a struggling state in sustainable democracy due to failed institutional approach to offering alternative solutions to its dwindling democratic space, despite having begun as a democratic state in 1971.

How can we be expected to tackle crime when there are more criminals than police? A criminal can walk freely because he knows that we don’t have the manpower to arrest him” (International Crisis Group 18). This is almost three times higher than the recommended ratio by the United Nations at 1:450. As part of the larger Judicial system, Police institution is at the bottom line in making arrests, organizing prosecution charges, and assisting the judicial panel in justice delivery.
