As part of your homework during those weeks without classes, please find attached a grid you need to fill in with the required information from the texts in annex. They all deal with shoot-outs that traumatized Americans. Also keep in mind that there are shootings every year, therefore the list of gun massacres in the document is far from being exhaustive.

NB: In class I would have made you worked in groups, with oral interaction activities yet you can see it is not possible given the CO-VID 19 confinement situation, hence you will work individually. 
Just a clue, so that you avoid lacking space when filling in the grid: you must draft the information about the Fort Hood shootings in the line "Group 5" (as two shoot-outs took place in that military base).
