Police forces are tasked with maintaining the peace, which means apprehending suspects without large scale destruction of property or loss of life. Those results are difficult to avoid when using the kind of heavy weapons you specify. You've seen one too many action movies. My cousin is in the SWAT Team for Vancouver, B.C., and they do really try to talk the person(s) out of the situation, but always have a good aim on their target. They will use tear gas and also dogs. By using the weapons you mentioned that could injure innocent by-standers or shopkeepers and possibly blow out half a city block.
There are three kinds of grenades. Antipersonnel grenades are used against people. There are fragmentation grenades, which break up when they explode and scatter, at high speeds, pieces of metal which injure or kill whoever you used the grenade against. There are also distraction grenades which create a loud noise and bright flash of light to stun the target...while they're stunned, you can rush in and take them into custody. (SWAT teams love distraction grenades.) Smoke grenades produce thick clouds of smoke. There are white smoke grenades used to conceal troop movements, and colored smoke grenades used for signaling. Product-delivery grenades come in two varieties. The first are White Phosphorous (willy-pete), which is an incendiary agent. The other are Tear Gas grenades.
