The NEGATIVE about crossbows is that they can easily be used to kill and take deer outside of legal shooting times without detection
So can a compound.
With a bow, where you need one hand to hold the bow and another to draw it back, there is no holding a light. You can't see the pins well enough to take a shot after legal shooting hours and even if you were tempted to try and sneak in a silent shot after legal shooting time you would not be able to see well enough to do it.
You can use the same types of sites on compounds that you can on crossbows. Also, I use to know a group of guys that poached with compounds all the time. One guy drove and help the light and the other guy rode in the back with a coupound. There was eough residual light from the spotlight to see the pins on his bow and he would just set up, draw, anchor and let it fly. If someone wants to poach they are going to poach it's a simple as that.
Now with a crossbow, you can easily sit in your treestand as long as you want .... and just flip on that flashlight and snuff deer with no one the wiser. I
That is again quite irrelevant and can also easily be accomplished with a compound as well. I have seen several people with flashlights for stabilizers. I believe it's quite popular in Texas where hunting hogs at night is legal. I am sorry but your arguments just don't hold water.
